Marc Winegust’s review published on Letterboxd :
If you Love the Beatles, Eric Idle and parody, this great mockumentary is perfect for you.
The "Pre-Fab Four" Dirk, Stig, Nasty, and Barry take England and the United States by storm. It's basically a perfect parody of the entire career of The Beatles. From the Cavern club, Ed Sullivan Show to shot for shot remake of the "I Am The Walrus" it's just a perfect film.
The songs in this are perfect parody of different Beatles songs mixed together or just with a different tune. Personal favourite is "Ouch" (parody of Help!)
