Sir Elton John has some words of advice for his young friend Ed Sheeran.

Appearing on the George Ezra and Friends podcast this week, the legendary “Tiny Dancer” singer spoke about Sheeran’s incredible string of success, but also warned that it likely won’t last forever.

“You have a heyday and you have a rest, and the heyday can never be replaced,” John said.

Referring to his own incredible string of No. 1 songs and albums in the 1970s followed by a relative slump, the 71-year-old explained, “After that I had the common sense to know I’m not going to have a No. 1 every time straight away. I knew someone else would take over. It’s cyclical.

“Ed will go through that and I’ve talked to him about it,” John added. “I’ve said, ‘There’ll come a time where this won’t happen every time and you have to accept that.'”

John also pointed to the fact that Sheeran’s songs are still on the Billboard Hot 100.

“It’s like, ‘Why? How many times do you want to listen to these things?'”

John has sold more than 200 million records over his 50-year career, and is about to embark on a three-year final world tour.
