Pharrell Williams performed 'Happy' like a man who has performed 'Happy' 10,000 times already this year at tonight's Grammys, wearing a bell boy outfit and conversing with a disembodied voice about hot air balloons that go to space.
Viewers were promised a "very special" performance of his world-conquering track and weren't disappointed, with its omnipresent chorus getting a new unhinged version, full of apocalyptic, stabbing strings. Basically what it must sound like in Pharrell Williams' head.
The performance featured a bizarre intro in which he did a sort of mime act and remarked: "I'm a hot air balloon that could go to space... With the air like I don't care so baby by the way."
He explained the bell boy outfit by saying he "lives to serve" his fans.
Sia's Chandelier was probably the other most talked about performance of the night, with Kristen Wiig donning a nude leotard and dancing for her .
Beyonce also sang to a chorus of 'prayer hands' emojis on Twitter and Kanye West performed twice, once alone and once with Rihanna and Sir Paul McCartney.
Most importantly, Kim Kardashian arrived to the ceremony dressed as Nature Boy Ric Flair .

Her look, made by Riccardo Tisci for Givenchy was something of a Moulin Rouge ensemble, including a very tight leather corset, thigh high boots and a net hat.
Grammys 2015 red carpet Iggy Azalea in Armani Prive This dress was custom made for Igg Azalea by Armani Prive which may explain the flawless fit. Whilst the dress is pretty spectacular in itself we applaud Iggy's choice of hairstyle which is a nice contrast from all the high ponytails and boho waves.
Grammys 2015 red carpet Rihanna in Giambattista Valli couture Rihanna plucked this dress right off the catwalk from last week's haute couture shows in Paris. Everything about it from the colour to the sheer volume adds to the dramatic impact that makes it the perfect choice for Rihanna.
Grammys 2015 red carpet Kim Kardashian in Jean Paul Gaultier Debuting a newly cropped hairdo, Kim Kardashian and her new found passion for high fashion opted for Jean Paul Gaultier. It's low cut (standard Kim) and the slightly oversized fit is actually working for her.
Grammys 2015 red carpet Nicole Kidman in Thierry Mugler Nicole Kidman like to toe the line when it comes to her sartorial choices. This Thierry Mugler dress was no different, safe but nothing spectacular.
Grammys 2015 red carpet Beyonce in Proenza Schouler Beyonce looks every inch the reigning Queen of pop in this black less low-neck gown. Black embroidered lace is clearly a trend for the evening, it would have been nice to see Beyonce in something a little more original.
Grammys 2015 red carpet Miley Cyrus in Alex Vauthier Miley Cyrus was surprisingly covered up in this black design which is actually rather modest for the popstar but naturally had a few raunchy cut-outs.
Grammys 2015 red carpet Gwen Stefani in Atelier Versace Gwen Stefani proved that it is possible to look formal in something other than a floor length gown in this jumpsuit made by Atelier Versace.
Grammys 2015 red carpet Chrissy Teigan in Emilio Pucci The American model went for an all white gown by Emilio Pucci. The dress may have a high neck and long sleeves but with cut-out details that go all the way up the dress and down the sides keep it Grammy appropriate.
Grammys 2015 red carpet Ariana Grande in Versace The Grammy nominee opted for a very glam dress by Versace. The one-shoulder dress featured silver detailing all set off with a high pony; a great formal gown without being too grownup for the 21 year old pop star.
Grammys 2015 red carpet Taylor Swift in Elie Saab A bright green assymmetric hemline dress for Taylor Swift. The popstar adds a playful pop of colour with bright pink shoes.
Grammys 2015 red carpet Anna Kendrick in Band of Outsiders Anna Kendrick opted for a classic black tuxedo shoot. Whilst this is undoubtedly stylish, at the Grammy red carpets it's perhaps a little serious.
Grammys 2015 red carpet Rita Ora in Prada A glamorous look for Rita Ora even it's so bright you can't actually look right at it. A little too disco ball perhaps.
Grammys 2015 red carpet Jessie J in Ralph & Russo A heavily embellished gown for Jessie J. Black beaded gowns can have a tendency to look gothic especially against Jessie's dark hair but the sheer layers lift the look and give it a modern twist.
Grammys 2015 red carpet Nicki Minaj in Tom Ford In the past Nicki Minaj has picked some unusual looks, for this year's awards she dared to bare in a plunging neckline black gown by Tom Ford.
Grammys 2015 red carpet Ciara in Alexandre Vauthier Couture Is it a bird, is it a plane? No but it's alot of fabric. There's way too much going on here, the volume of fabric and the train overwhelm Ciara.
Grammys 2015 red carpet Jennifer Hudson in Tom Ford Jennifer Hudson opted for a very simple white strapless dress by Tom Ford which while nice enough, won't won't win any best dressed lists.
Grammys 2015 red carpet Katharine McPhee in Pucci The American singer was a breath of fresh air on a red carpet dominated by black and white gowns, in this salmon pink Pucci gown.
Grammys 2015 red carpet Lady Gaga in Brandon Maxwell Lady Gaga may be in a sparkly silver gown with low neckline and a thigh high split but for Gaga this look is really rather ordinary.
Grammys 2015 red carpet Annie Lennox Less is sometimes more as Annie Lennox proves in this floor length black shift dress. Simple and classic.
Grammys 2015 red carpet Katy Perry in Zuhair Murad Fresh from her appearance at the Super Bowl, Katy Perry pulled all the stops out in a silver spangled dress by Zuhair Murad, right off the runway. She accessorised the look with purple hair.
Grammys 2015 red carpet Miranda Lambert in Gabriela Cadena A lesson in how to update that trusty black dress, just add neon straps.
Grammys 2015 red carpet Gwyneth Paltrow in Saint Laurent Amongst a sea of black and silver sequins, Gwyneth Paltrow's shiny red mini dress is refreshingly different, adding some much needed colour to the event.
Grammys 2015 red carpet Meghan Trainor in Galia Lahav An off the shoulder black lace and khaki gown for Meghan Trainor. The two tone effect stops the whole look becoming too gothic.
Grammys 2015 red carpet Giuliana Rancic E! news presenter Giuliana Rancic made her entrance in a sheer panel jumpsuit, which she swiftly told viewers she couldn't wear underwear with, in case you were wondering.
Grammys 2015 red carpet Kelly Osbourne in Christian Siriano Fellow E! presenter Kelly Osbourne went for a demure look, (well if you discount the purple hair) in a monochrome floor length gown.
Grammys 2015 red carpet Paris Hilton in Charbel Zoe Couture Yes another low-cut, glittery dress, this time on socialite Paris Hilton.
Grammys 2015 red carpet Rita Ora in DSquared2 Rita Ora made an outfit change later in the evening, but the popstar should probably have stuck to her silver Prada number; all those ruffles and multicolour print is doing nothing for her.
Grammys 2015 red carpet Kendall Jenner in Elie Saab Kendall Jenner opted to go along with the theme of the evening in black halterneck lace gown by Elie Saab.
Grammys 2015 red carpet Khloe Kardashian in Constantina & Louise In a look reminiscent of Beyonce's Proenza Schouler dress, Khloe vamps it up in this low-cut black lace embroidered gown with bold red lips.
Grammys 2015 red carpet Kylie Jenner Kylie Jenner broke away from her sister's gothic looks with a white beaded gown with a couple of cut-outs on her midriff. It's a conventional look for the sibling that is has built a reputation as the more adventurous of the clan.
Grammys 2015 red carpet Miranda Kerr The model attended post-Grammy parties in a 60s inspired metallic mini dress.
Grammys 2015 red carpet Jessie J Whilst Jessie J's ceremony gown was rather dazzling, we can't help feel that this monochrome crop-top and pencil skirt number feels a little bit more like her.
Grammys 2015 red carpet Lady Gaga Gone is the bizarre costumes of previous awards ceremonies, instead Lady Gaga is channelling a vintage screen siren in this black beaded look complete with feather boa.
Grammys 2015 red carpet Rihanna in Maison Margiela From the pretty in pink fairytale princess gown Rihanna arrived in to this androgynous suit. Rihanna couldn't have possibly picked two more completely different but equally brilliant looks.
Grammys 2015 red carpet Madonna in Givenchy Haute Couture by Riccardo Tisci If her first outfit was anything to go by, the second performance look was set to be a winner. Red and black matador inspired bodysuit complete with cape.

Grammys 2015 red carpet Gwen Stefani in Atelier Versace Gwen Stefani's choice of a jumpsuit instead of gown for the arrivals sealed her place on best dressed lists, this second dress also by Atelier Versace is an equally great look.
Grammys 2015 red carpet Ariana Grande A little more daring than her first icy white attempt. As with many other designs seen at the awards, this purple performance gown had strategic cut-outs.
Grammys 2015 red carpet Beyonce From one extreme to the other, Beyonce went from a gothic black red carpet arrival look to angelic white beaded dress complete with tulle cape.
Grammys 2015 red carpet Katy Perry in Valentino This isn't the first time we've seen this look Valentino caped look - Solange Knowles wore it to get married - equally as amazing second time around.
