Elton John is believed to be planning to sing Don’t Let The Sun Go Down On Me at George Michael's funeral.
According to reports, the singer will honour his late friend by singing a version of the song which was a hit duet for him and Michael in 1992.
53-year-old Michael was found dead at home in London on Christmas Day by his partner Fadi Fawaz.
Elton paid musical tribute to another friend, Princess Diana, at her funeral in Westminster Abbey, following her death in a car accident on August 31, 1997.
On that occasion, he sang Candle In The Wind, with some new lyrics supplied by Bernie Taupin, who had originally written the song as a tribute to Marilyn Monroe.
At George Michael's final ever performance on October 17, 2012 in London's Earls Court, the then 49-year-old singer performed a 23-song set at the gig.
The date was the singer's final show on his 75-date Symphonica Tour of Europe.
At that show, the Michael told the crowd of fans "London, you have made the last night f*****g perfect.
"It has truly been a privilege to play with these musicians for the last year and we want to say a big thank you to you all."
