on, Sutcliffe decided to leave the band early that year and resume his art studies in Germany. McCartney took over bass. Producer Bert Kaempfert contracted what was now a four-piece group until June 1962, and he used them as Tony Sheridan's backing band on a series of recordings for Polydor Records. As part of the sessions, the Beatles were signed to Polydor for one year. Credited to "Tony Sheridan & the Beat Brothers", the single "My Bonnie", recorded in June 1961 and released four months later, reached number 32 on the Musikmarkt chart. After the Beatles completed their second Hamburg residency, they enjoyed increasing popularity in Liverpool with the growing Merseybeat movement. However, they were growing tired of the monotony of numerous appearances at the same clubs night after night.

He later recalled: "I immediately liked what I heard. They were fresh, and they were honest, and they had what I thought was a sort of presence ... [a] star quality."

Epstein began negotiations with record labels for a recording contract. To secure a UK record contract, Epstein negotiated an early end to the band's contract with Polydor, in exchange for more recordings backing Tony Sheridan.

He immediately complained to Epstein about Best's drumming and suggested they use a session drummer in his place.
