Singer-songwriter Sir Elton John thinks artists who don't want their music played on the Fox musical-comedy Glee need to lighten up.

The Foo Fighters are the latest rock stars to say “no” to Glee creator Ryan Murphy.

“It's every band's right, you shouldn't have to do fucking Glee,” Foo Fighters frontman Dave Grohl told The Hollywood Reporter. “And then the guy who created Glee is so offended that we're not, like, begging to be on his fucking show. … Fuck that guy for thinking anybody and everybody should want to do Glee. … It's not my thing.”

Guns N' Roses frontman Slash called Glee “worse than Grease” in turning down the show.

Appearing Thursday on NBC's late night talk show The Late Show with Jimmy Fallon, Sir Elton railed against the artists.

“There's a big debate going on about the Glee thing at the moment. A lot of bands say we don't want our stuff on Glee. Like lighten up you assholes,” Sir Elton said.

“This is a compliment,” he added. “Also it sends a positive message out. What the hell is wrong with you guys.”
