Written by Idle and Innes, "All You Need Is Cash" documents the rise and fall of the Rutles, paralleling much of the history of the Beatles. The project was given extra recognition through Harrison's support; as well as providing ideas, he supplied Idle and Innes with a copy of the Beatles' long-planned documentary, "The Long and Winding Road" (eventually re-titled "The Beatles Anthology" and released in 1995). Idle drew inspiration from this 1976 version of the documentary, as compiled by Neil Aspinall, and was granted permission to use some of the archival footage to tell the Rutles' story.
