I was there when the Beatles came out. Nothing like it. It was like finding a well on an oasis...It's really an underrated (maybe "underdiscussed" is a better word) aspect of the Beatles that they were a just plain old, in the room, all together in one place, absolutely drop dead great live rock n' roll, pop, and rhythm-and-blues band. Stone Cold Killers. That live at the BBC album is great, and then after years of not doing it, they went up on that rooftop and absolutely crushed. The Beatles that you hear on BBC stuff from say '63 are just orders of magnitude better than say the Stones at the same point (even when you compare apples to apples like dueling Chuck Berry covers).
