On 2 January, day one of the Twickenham film shoot, Harrison introduced "All Things Must Pass", and the band worked on the song intermittently over the next four days of filming. In the search for a suitable musical arrangement, Harrison stressed his preference for a "feel" akin to the Band, a suggestion that resulted in Lennon switching from guitar to Lowrey organ, a keyboard favoured by the Band's Garth Hudson. During the Twickenham rehearsals, the Beatles also discussed the idea of Harrison performing "All Things Must Pass" solo for inclusion in the proposed film.
