"Two of Us" was originally a hard rock song. In the "Let It Be" film, McCartney and Lennon sing the song "rocker" style into the same microphone. McCartney had never been satisfied with this style, which he said was "chunky." And so on 24 January, he and the band reworked it. Lennon had ideas about how the song might sound if Stevie Wonder performed it, and just before revisiting the song, the band had run through the Everly Brothers hit "Cathy's Clown". With these influences and a move from electric guitar to acoustic, the song transformed into the gentler, stripped-down version that fans know today. The Beatles performed a finished version of the song live at Apple Studios on 31 January 1969; this performance was included in both the "Let it Be" film and album.
