Elton John told BBC Radio 2 that he would "probably" perform at the wedding of Prince William and Kate Middelton.
He hinted that he could be performing outside Westminister Abbey where the couple will wed on April 29, 2011.
"I'll probably be outside busking," he said.
The 63-year-old British singer famously performed Candle in the Wind, a remake of his 1973 hit, at the funeral of William's mother Princess Diana in 1997.
He was on BBC Radio 2 to plug his new album with Leon Russell, The Union.
