Campbell was very open about his experience with Alzheimer's, even turning it into a song - the last one he recorded - which was titled: 'I'm Not Gonna Miss You'.

Musicians from many different genres paid tribute on Twitter.

"Glen Campbell was one of the greatest voices of all time. I will always love you, Glen!" Dolly Parton wrote.

"I'm very broken up to hear about my friend Glen Campbell. An incredible musician and an even better person. I'm at a loss. Love & Mercy," Brian Wilson added.

"God bless and peace and love to Glen Campbell thanks for the music The real rhinestone cowboy and love to all his family," Ringo Starr remembered, with Miley Cyrus adding: "Miss you already."

Over on Instagram, Lenny Kravitz wrote: "Besides being an amazing solo artist, Glen Campbell was also a genius studio musician - as part of the Wrecking Crew - playing on recordings from The Beach Boys to Frank Sinatra. He was pure talent, heart, and courage. Rest In Peace brother. You brought us a lot of joy."
