Mark Ronson may quit performing onstage in the next five years.

'The Bike Song' hitmaker said he thinks he's getting too old to keep performing for too much longer and has hinted he will concentrate on producing records above other endeavours in the future.

He said: "I do try to focus on the music and not get caught up in all the other s**t, but... Well, I'm 35. I'm probably in the last five years of performing onstage.

"That's the ideal. To do well enough that you just don't worry about dipping out of The Game for a year and having everyone forget you."

He also used Beatles producer George Martin as an Example he'd like to live up to.

He added: "I mean George Martin wasn't going around peddling his latest brand of polo shirt. He stayed in the studio and that's why he has a brilliant legacy of music."

Mark - who admits he can be a little neurotic - also said he doesn't feel like he was born to perform onstage.

He added: "I get nervous before I go on stage because I'm not a born performer. I only started playing guitar three years ago and I only started singing, like, yesterday. I do think I throw obstacles in my own

path, and ratchet up the neurosis that way. But there are worse problems to have, I think."
