When George Martin signed The Beatles and "Love Me Do" was to be recorded, he told them that they had to get rid of Pete Best as he wasn't up to the standard of the others in the group. John and Paul said that they had been thinking the same thing. George Martin didn't know that they had been thinking this and that they had Ringo in the wings ready to step in. As a result, he had a session drummer at the studio for the recording. They ended up recording two versions of the song, one with the session drummer and one with Ringo. As George Martin had not heard of Ringo, he didn't know whether he would be good enough or not, hence the second version without Ringo. If you listen to both versions of the song back to back, they are quite different. So if you are curious as to what The Beatles might have sounded like without Ringo (or Pete Best), two versions of "Love Me Do" are out there with two different drummers.
