Noel Gallagher has laid into "middle-class" acts like Ed Sheeran and Mumford and Sons after they changed their minds about appearing at next week's Teenage Cancer Trust charity shows at the Royal Albert Hall.
"Everybody says 'Yes' to your face, everybody," said Gallagher, who is organising this year's event.
"And then the agent will call and their management will call and then their PR will call and say, 'Ah, they're going to be in Australia at the time.' Really? Well they never said that to me."
"I'd talk to Ed Sheeran and Mumford & Sons thinking, 'I'll just f***ing do the seven nights myself; what the f**k am I asking these people for?' I got let down a lot.
Gallagher feels the issue has something to do with a class divide.
He added: "What's interesting is all the working-class bands said 'Yes' straight off the bat, no f***ing inkling of when it was.
"The middle-class bands said 'Yes' and wriggled out of it. I dunno what that means, but it must mean something. It was an interesting summer.
"But I will say, if the people that blew me off but said they'll do it next year actually do it, it might be the greatest event since Woodstock."
Gallagher's final line up for the Teenage Cancer Trust shows, which take place at the Royal Albert Hall from March 19, include shows headlined by himself, Kasabian, Primal Scream, Ryan Adams, and comedians Russell Brand and Noel Fielding.
