Elton John opened the holiday season run of his ongoing "Million Dollar Piano" residency on Dec. 28 in Las Vegas at the Colosseum at Caesars Palace. The 6-time Grammy winner's hit-filled 18-song setlist included a moving tribute to the late British pop star George Michael, who died of heart failure at his London home on Christmas Day.

The pair had performed the ballad at Live Aid in 1985 and re-recorded the song together as a chart-topping 1992 duet.

The multi-platinum seller performed the song in front of a massive poster of his late friend projected above the stage on an LED screen. Fan-shot footage of a section of the performance has been posted at Instagram and can be viewed here.

“I am in deep shock,” wrote the “Rocket Man” hitmaker at his official Twitter account after learning of Michael's tragic passing. “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."

Rumors have been circulating that John plans to perform at the “Careless Whisper” hitmaker's funeral. No official date or location has yet been announced for the ceremony.
