If you would like to get a general idea of what a Beatles concert was like back in the day, this might be worth your while. The artist who plays John Lennon is very good. "Paul," however, is waaaay over-played in this act, and both "George" and "Ringo" are unremarkable.
Unfortunately, the show begins with a horrible comedy act by the band's producer, who has a HUGE ego and should be prosecuted for impersonating a comedian. That segment was a complete and annoying waste of time.
The REAL DEAL is the band known as "The Fab Four." They play every song and every note EXACTLY as it is supposed to be, all of it live, nothing on tape. In a Fab Four show, you literally need to remind yourself now and then that you are not watching the actual Beatles. The Fab Four's "Paul" has every note and mannerism down pat. The same "Paul" also plays in the Beatles tribute band known as "Rain," which is better than "1964 The Tribute" but not as good as "The Fab Four."
The bottom line is that it is readily apparent that the 1964 Tribute has copied everything from the Fab Four, the group they strive (but fail) to emulate.
