I didn't realize they came to an end before the 70's.
I did how ever pickup three Beatles DVD sets for Beatle luv'n buddy of mine at a yardsale yesterday - one of them was still sealed in it's original wrapping.
The Beatles Help (two disk set)
The Beatles Hard Days Night (two disc set)
The Beatles Uncensored - see the Beatles in historic live performaces and interviews (still sealed)
Anyways - it's a happy merry christmas present for him
