Scottish rockers Biffy Clyro, who picked up the Best British Band prize at last night's (February 27) NME Awards, have revealed that they were offered the chance to work with both Robbie Williams and Leona Lewis.

Frontman Simon Neil told the Daily Star newspaper that they turned both opportunities down, but they would reconsider doing something similar in the future once their own band has 'slowed down':

"Writing for others is something I'd love to do once we slow down as a band. But if you write a song that you think is one of the best ever, and it's not for our band, I don't know if I'd be happy giving it away."

"We got asked to have a writing session with Leona Lewis and play on Robbie Williams' record. I'm a wee bit selfish about it, plus we've got enough side-projects, so we've got other outlets. It's a beautiful thing to sit and write songs all day."

Meanwhile, Biffy Clyro are set to headline this year's Reading and Leeds Festivals in August.
