The funnyman was competing with the soundcheck for the low-key charity gig as he celebrated his daughter Sunny's third birthday at his Hollywood home last week (ends04Nov11) and when he complained about the noise, he was stunned to find out that rock royalty were performing just over the wall.
He says, "I started going, 'Hey keep it down over there,' and they're like, 'Sorry, we're getting ready for tonight... The Who's coming!'
"It was awesome. Me and my giant family... The Who played eight tunes, Foo Fighters, Robert Plant sang all these Led Zeppelin tunes and we got to listen to the whole thing."
