Thanks, some of those pictures was when Stu Sutcliffe and Pete Best was in the band, before Ringo.
Paul replaced Stu (Stu could not play Bass really well)as the bass player,(Paul played regular guitar before that) and Ringo replaced Pete Best on drums.
Stu died, and Pete left the band. (Pete wasn't "good enough" for George Martin)
P.S., thanks Palerider and Freddy. Freddy, those skins are great!!
