Music by The Beatles seems finally set to become available on iTunes. Sir Paul McCartney gave the most definite indication yet of a time-frame for the release of music from the band through digital music services, telling Contact Music: "It's down to fine-tuning, but I'm pretty sure it'll be happening next year, 2008."

Sir Paul added: "You've got to get these things right. You don't want to do something that's as cool as that and in three years time you think, 'Oh God, why did we do that?'"

But, he said: "There's just maybe one little sticking point left, and I think it's being cleared up as we speak, so it shouldn't be too long."

Apple last month added an extensive catalogue of music from George Harrison to its iTunes catalogue, meaning the service now offers music from all four of the members of the band.

Speaking earlier this year, Harrison's widow, Olivia, explained that agreements to make music from The Beatles available through online music services were being made, but warned that fans might have to wait until 2008 for music to be made available.
