‘Love Me Do’ at 50: Five fab facts about the Beatles’ first single

1. That’s not vibrato, that’s nerves
When the Beatles first congregated Sept. 4 in Abbey Road studios to record “Love Me Do,” they had overhauled the arrangement and John Lennon now had a harmonica part. But Lennon’s harmonica got in the way of his singing the song’s a cappella chorus tag so the vocal duties needed to be changed as well, said producer George Martin. That left a very anxious, 20-year-old Paul McCartney to go it alone on the chorus. “Until that session John had done it,” said McCartney in Barry Miles’ “Many Years From Now.” “I didn’t even know how to sing it … I can still hear the nervousness in my voice.”
