Noel Gallagher's been telling XFM his theory on why the BRIT Awards was so dull this year.
"You can't do anything. There's not the people around any more," he explained.

"Ten... fifteen years ago it was a lot of people there who couldn't believe their luck. We'd all come from the streets and it was like 'how've we ended up here?' and it was great and now its just boring."
He was talking to us after playing the Wembley Arena last night - alongside Kasabian and Jake Bugg - for Comic Relief.
