The singer will perform the pair’s 1991 duet

Elton John is reportedly set to perform at his friend, George Michael’s funeral. Metro reports that John will perform the pair’s 1991 duet, “Don’t Let The Sun Go Down On Me” at one of two potential funeral services planned. John and Micheal are long time friends who performed the track during a Live Aid concert in 1985 and later at Michael’s own Wembley Arena concert in 1991.

The world was shocked when it was reported that Michael passed away on Christmas Day from heart failure. The singer died at the age of 53 at his home in Goring in Oxfordshire, located in Southeast England.

“It is with great sadness that we can confirm our beloved son, brother and friend George passed away peacefully at home over the Christmas period,” the publicist says in a statement. “The family would ask their privacy be respected at this difficult and emotional time. There will be no further comment at this stage.”

Following Michael’s death, John shared his thoughts via Instagram.

“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,” John writes with a picture of the pair.

Reports also claim that there may be two ceremonies for Michael. One would be for family and close friends while the other would be for his fans. It is also believed that Michael will be buried next to his mother, Lesley, in Highgate Cemetery in North London.
