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. Trying to come up with a conclusion for the film, it was suggested that the band play an unannounced lunchtime concert on the roof of the Apple building. On 30 January, the Beatles and Preston played on the rooftop in the cold wind for 42 minutes, about half of which ended up in the film. The Beatles started with a rehearsal of "Get Back," then played the five songs which are shown in the film. After repeating "I've Got a Feeling" and "Don't Let Me Down," takes which were left out of the film, the Beatles are shown in the film closing with another pass at "Get Back" as the police arrive to shut down the show. On the 31st, the last day of filming and recording, the Beatles reconvened in the Apple building's basement studio. They played complete performances of "Two of Us," "The Long and Winding Road," and "Let It Be," which were included in the film as the end of the Apple studio segment, before the closing rooftop segment. A rough cut of the movie was screened for the Beatles on 20 July 1969. Lindsay-Hogg recalled that the rough cut was about an hour longer than the released version: "There was much more stuff of John and Yoko, and the other three didn't really think that was appropriate because they wanted to make it a 'nicer' movie. They didn't want to have a lot of the dirty laundry, so a lot of it was cut down."[18] After viewing the released version, Lennon said he felt that "the camera work was set up to show Paul and not to show anybody else" and that "the people that cut it, cut it as 'Paul is God' and we're just lyin' around ..."[18] Lindsay-Hogg omitted any reference to Harrison leaving the sessions and temporarily quitting the group, but managed to keep some of the interpersonal strains in the final cut, including the McCartney/Harrison exchange which he had captured by deliberately placing the cameras where they would not be noticed. He also retained the scene that he described as "the back of Paul's head as he's yammering on and John looks like he's about to die from boredom."[19] In early 1970 it was decided to change the planned name of the film and the associated album from Get Back to Let It Be, matching the group's March 1970 single release. The final version of the film was blown-up from full-frame 16 mm to 35 mm film for theatrical release, which increased the film's graininess. To create the wider theatrical aspect ratio, the top and bottom of the frame was cropped, necessitating the repositioning of every single shot for optimal picture composition. While the album Let It Be contains many of the song titles featured in the film, in most cases they are different performances. The film has additional songs not included on the album. The following songs are listed in the order of their first appearance, with songwriting credited to Lennon–McCartney except where noted.
