Day Tripper
"Day Tripper" was written early in the "Rubber Soul" sessions when the Beatles were under pressure to produce a new single for the Christmas market. John Lennon wrote the music and most of the lyrics, while Paul McCartney contributed some of the lyrics. Lennon based the song's guitar riff on that from Bobby Parker's "Watch Your Step", which had also been his model for "I Feel Fine" in 1964. In a 1980 interview, Lennon said of "Day Tripper": "That's mine. Including the lick, the guitar break and the whole bit." In the 1997 book "Many Years from Now", McCartney claims that it was a collaboration but Lennon deserved "the main credit".
