I Want You (She's So Heavy)
During the sessions, the Beatles played many songs that were not featured in the film. Some would end up on "Abbey Road" ("I Want You (She's So Heavy)", "She Came in Through the Bathroom Window"); others were destined for future albums by McCartney ("The Back Seat of My Car", "Teddy Boy", "Every Night"), Lennon ("Gimme Some Truth", "Child of Nature" – later reworked as "Jealous Guy"), and Harrison ("All Things Must Pass", "Isn't It a Pity"). The group also experimented with some of their previous songs ("Love Me Do", "Help!", "Lady Madonna", "You Can't Do That") and played "I Lost My Little Girl" – which was the first song written by McCartney, when he was 14.
