I watched the movie, the documentary the film, the event of the year and all I have to say is this:
If you have ever been in a rock and roll band, been around a rock and roll band or knew someone who was or is in a rock and roll band then you know exactly what the Beatles were going through, what they were up against and why things turned out the way they did.
That also goes for solo acts, folk duos, swing trios, string quartets and whatever the quintet version of a group might be called.
Musicians, by and large are nuts. Creative people tend to be so and what else can I say except they were the Beatles.
See ya round the clubs.
