Questions regarding The Lost Concert (a documentary in cinemas soon) | Fab Forum | The Beatles Bible

No idea if people have seen that the complete Washington DC concert from 1964 is going to be screened as part of a 90 minute documentary in selected cinemas in the US on May 17th and 22nd.

My questons are how does this and things like the Ed Sullivan shows get released when they arent sanctioned by Apple? Is it because the legal stance changes since its live or was it part of the original contract signed that the rights to the music belong to the promoter of the gigs? And if so why arent there legal live beatles concerts on cds and dvd out there? If they can put out the concert in cinemas why cant they release the soundtrack legally?

For a long time in beatle documentaries you had to put up with lousy tribute bands but now you can hear live beatle versions of beatles songs and no one bats an eyelid.

There is probably a simple answer.
