The older I get, the more I appreciate what a phenomenon The Beatles actually were.
When you think every band has a set line-up, which although can change, you never get people associated with them as official members, which makes it more incredible that there was always a case for a fifth Beatle - Sir George, Brian Epstein and Stuart Sutcliffe. Theres even a wiki page dedicated to it.
But for me, when it comes down to the music, Sir George has to fill that role.
He was Algernon to the Fab's Bash Street Kids.
RIP, Sir George.
