JAT says 'Hi'.Well maybe not, I haven’t watched it but when you talk of Boy Bands, One Direction is arguably the biggest one ever.
Applying the general definition of being either in their teens or early twenties when they formed would make them one I guess.When they previewed this the other day on the BBC breakfast programme, the prick of a presenter (don`t know his name), described the Beatles as being a boy band.
A quick Google suggests 600 million Beatles sales versus 130 million for the Backstreet Boys.Backstreet Boys outsold the Beatles anyway apparently
