Dig It is credited to all four members of the Beatles, one of just a few songs with this distinction. (Compare it with Flying (Magical Mystery Tour).) It was composed and recorded at the Apple Studios in a single, improvisational process, in two sessions (January 24 & 26, 1969). The public first heard this track on May 8, 1970, when the Let it Be album was released in the UK (May 18, 1970 in the US). The production of the song was simple: Lennon is the lone vocalist, engaging in a free-association of extemporized lyrics. The song's chord structure is the familiar rock sequence of I-IV-V. Paul plays piano, George plays the sole guitar, and Ringo is on drums. Billy Preston is credited with the Hammond Organ and George Martin supplied the "shaker" (session number 2). On the Let it Be album, only 49 seconds of Dig It survived, but the original recording is considerably longer. The January 24th version was almost 7 minutes long. The January 26th version was almost 12½ minutes. The portion from 8'52" to 9'41" was used in the Let it Be release. The version used in the film, Let it Be, is the same segment, but a bit longer.
