The LAST NITE hitmaker, who is dating Hollywood actress Drew Barrymore, insists he will retire from the band when they have nothing new to offer.
He says, "If we could still be a band that is honest to itself and able to reflect its current status, then we will (make music and go on tour until we get old).
"But if we hold on to something that we were in the past, than we won't.
"I don't want to end up like The Rolling Stones. They are old men trying to be young guys. That's sad."
