And the answer is a definitive no. Not even for $250m.
Roger Waters, the one-time leader of Pink Floyd, who quit the line-up two decades ago, has revealed they were offered the cash as pure profit for one last tour. At £136m, it would have been the equivalent of £1 for every album they have sold in the last 38 years.
Yet the band, famous for its song "Money" with a line that advised "grab that cash with both hands and make a stash", turned the offer down.
It came shortly after the quartet agreed to their one-off performance in Hyde Park, a show that few fans ever believed was possible as Waters appeared with the band for the first time since 1981. His departure was followed by a bitter legal battle.
Waters, speaking for the first time since Live8, said he "really loved" playing with the band again.
And in an interview for the October edition of Word magazine, out on Thursday, he held out some possibility of the band re-forming again.
"I hope we do it again. If some other opportunity arose, I could even imagine us doing Dark Side of the Moon again - you know, if there was a special occasion. It would be good to hear it again."
