I think The Beatles are so over hyped; it was nearly 50 years ago for goodness sake? Were they a good band? Yes, but they were not Gods. As a certain Dan Le Sac and Scrobious Pip pointed out - "They were just a band?".
Having said that, I would have had both The Beatles and the Stones in at the start of 50 years of British music before including the mighty Zep (Bonham Junior on drums), The Who, and some incarnation of the Bluesbreakers, if they could put their egos aside for one night. The Seventies would have some disco, some glam rock, Bowie, Steve Harley, punk, (Pistols, Stiff Little Fingers, Stranglers) and The Specials. The NWOBHM would take us into the Eighties and I would hand over to someone else as I drifted away from music around here for a while.
