In 1963 the English Merseybeat band the Fourmost made a recording of the song at the EMI Studios, produced by George Martin.
In Paul McCartney's authorized biography, Barry Miles seems to refer to this song as a collaboration.
In America, the song was recorded by the short-lived West Coast band, The New Breed.
[4] The record was a regional success in the Bay Area (their home base) and other parts of California, but not nationally.
Recordings of "I'm in Love" as the Beatles may have performed it are available on the 1989 album by Bas Muys entitled Secret Songs: Lennon & McCartney[5][6] and on the 1998 release It's Four You by the Australian tribute band The Beatnix.
