Eurovision is back with more entertaining performances for its 60th year.
After Conchita Wurst flew the flag for gay and transgender groups in 2014, this year sees more acts hoping to promote tolerance through music on 23 May.
The song contest will welcome a Finnish punk band with learning disabilities, a partially paralysed Polish singer and a Romanian band singing to raise awareness of abandoned children left by their parents working abroad.
But there are still some weird and wacky entries too. Take a look at this year's contestants:
Five Eurovision 2015 contestants to look out for:
1) Australia – Guy Sebastian
To mark the contest’s 60th anniversary, Australia has been invited to take part as a one-off. Despite obviously not being part of Europe, the country has a long tradition of broadcasting the contest. But rather than choosing Kylie Minogue, Iggy Azelea or Sia – Australia has instead chosen Guy Sebastian, that well known former winner of Australian Idol.
2) Poland – Monika Kuszyńska
Poland’s contestant, who has been a wheelchair user since 2006 after being partially paralysed in a car crash, hopes to “build the bride of tolerance” this year with her song “In the Name of Love”.
3) Serbia – Bojana Stamenov
Serbia’s larger-than-life entry Bojana Stamenov has a big voice and a sense of humour to match (assuming she’s not taking herself seriously in her promotional photos). The former Serbia’s Got Talent finalist says: “I know how to knit and cook…But, watch out, my voice will blow up your mind.”
4) Finland - Pertti Kurikan Nimipäivät
Punk band Pertti Kurikan Nimipäivät (PKN) all have learning difficulties of some kind and will be performing in a bid to raise awareness of Down’s Syndrome. The band formed after meeting at a workshop for adults with learning disabilities and plan to perform “Aina Mun Pitää”, a song about daily frustrations.
5) The UK – Electro Velvet
Chances are, if you’re British, you won’t have heard of the UK’s entry for this year’s contest. Electro Velvet, a musical duo with an electro-swing sound, will be performing “Still in Love With You”, which has already had over 1.6 million views on YouTube.
