"Please Please Me" (1963)
When John Lennon and Paul McCartney first played "Please Please Me" for George Martin during their second EMI recording session on September 4th, 1962, the song was miles away from the uptempo tune that would become their first Number One. "At that stage 'Please Please Me' was a very dreary song," Martin recalled to historian Mark Lewisohn. "It was like a Roy Orbison number, very slow, bluesy vocals. It was obvious to me that it badly needed pepping up." He suggested they speed it up double-time, and suddenly they had a hit on their hands. "We were a bit embarrassed that he had found a better tempo than we had," admitted McCartney in The Beatles Anthology.
