Elton John paid tribute to his late friend George Michael last night, ABC reports, opening his show in Las Vegas with a performance of “Don’t Let The Sun Go Down On Me.” John and Michael performed the song together in 1985 before recording and releasing it as a duet in 1991, but last night, John performed it alone while projecting a photo of Michael onto the stage. Watch below.

I am in deep shock. I have lost a beloved friend – the kindest, most generous soul and a brilliant artist. My heart goes out to his family, friends and all of his fans. @GeorgeMichael #RIP
