The other Beatles thought Pete was a pretty good drummer, but then in Hamburg they heard and met Ringo. When the Beatles and Pete returned to Liverpool, Mona acted as the booking agent for what she considered "Pete's band". She got them introduced into the Cavern Club. Pete played on "My Bonnie" and the other tracks recorded with Tony Sheridan for Bert Kaempfert in Germany.

In November 1961, Brian Epstein became the Beatles' manager, and in April, 1962, Brian succeeded in getting them an audition with George Martin at Parlophone, which happened on June 6. By this time, both Paul and George were encouraging Brian to help them get rid of Pete, to bring on Ringo permanently, who had been filling in for Pete with the Beatles every now and then. In late July, George Martin commited to recording the Beatles. When George Martin told Brian that he didn't care for Pete, and that they would use another drummer on the sessions, he didn't know the Beatles were already thinking the same thing. Brian told him during a lunch time meeting in his office on August 15. Mersey Beat broke the news on August 23. Pete Best fans were outraged. Petitions signed by hundreds were received at Mersey Beat. Cries of "Pete Best Forever---Ringo, never!" were heard at the Cavern Club. The following Monday, one of the many scuffles outside the Cavern Club resulted in a black eye for George Harrison.
