ah there are a few familiar covers that grace my shelves as well =)
My uncle is a huge Beatles fan - he has every single song they ever published. Even some original (presumably bootleg-)recordings on tape. He kinda infected me.
If you ever come to London, go to Baker Street. Right next door (well, actually left) to the famous 221B is a Beatles shop where you can get everything from genuine autographs and photos to records and fanstuff.
