I don't have a favorite Beatles live performance. Why not? Because I think that their carreer as a live band was, in hindsight, a HUGE dissapointment. They stopped performing live before they reached their peak. Can you imagine how f*cking brilliant it would have been if The Beatles had played Woodstock in 1969 with a few backup musicians and with songs from their then most recent albums? That would've blown 'The Beatles at the Hollywood Bowl' and 'Live at the BBC' out of the water so incredibly hard.
