All-boy trio Busted have good reason to be boisterous, having topped the charts with their upbeat brand of rock-pop, and fans watching their every move.

Charlie Simpson, Matt Jay and James Bourne are just like your average posse of young lads, jostling for attention, raising their voices and swearing.

But mention the term 'boy band', and they settle down to argue they are different from, say, Westlife or Blue.

Busted are keen to argue they're not just another production-line act.

Chart-toppers Busted are keen to argue they're not a boy band - despite being a huge hit with teens.

'We're not a serious rock band, we're a pop band - but we're not a boy band,' says spiky blond James, least likely heartthrob but eloquent spokesman.

'To call us a boyband is seriously underrating us,' adds James.

He is quick to point out that both he and bandmate Matt Jay boast a ream of songwriting credits on their second album, A Present For Everyone.

Male pop acts have a notoriously short shelf life, but the bous from Busted aren't yet ready to put a sell-by date on their chart-ripping success.

'I think we've got more longevity,' says James, drowning out Charlie and Matt's chorus. 'Boy bands don't have a hand in what they do,' he adds.

As for the end of Busted: 'That's a bridge we cross when we come to.'

'At the moment people out there are loving it. I don't want to think of the time when they don't any more,' which is a poignant addition from Matt.

The past year has seen Busted become the best-selling British group apart from Coldplay - an act more likely to win older music fans' votes.

'We don't claim to write music that changes people's lives,' says James. 'Music that shouldn't be messed around with is really serious, but that's not what Busted is about.' The sudden intervention comes from Charlie, the fans' tall and handsome favourite, well-known for his pair of luxuriant eyebrows.

Teen trio Busted acknowledge that the future of the pop scene is changing.

'The singles market is dead. It's all about making albums now,' says Charlie.

'Pop music seems to be frowned upon all of a sudden and artists don't want to say they're pop bands,' says James.

Busted end with a dig at chart rivals Blue, who have Stevie Wonder on side in their bid for the Christmas No. 1.

'It should be Stevie Wonder featuring Blue. It's a bit much,' says James - keen to keep those old rivalries alive.
