The Rocket Man star said brothers Noel and Liam Gallagher were 'stupid sods' for cancelling some of their US shows in the Nineties as they failed to crack the US.
Speaking to UK's Absolute Radio, John said: 'They were enormous in Britain, they were enormous in America and they went over there and argued between themselves and cancelled the tour and they never broke America.
'You only get it once, and if you blow it, it's gone. You can't not regret that. I always thought: 'You stupid sods. You'll never get that opportunity again.''
