“My Bonnie” isn’t your typical Beatles song.
The lineup on this one isn’t John, Paul, George and Ringo.
It’s John, Paul, George, Pete and Tony.
Pete and Tony?
When this song was recorded Pete Best was still playing drums for the group.
Tony is Tony Sheridan, who performs the song (and The Beatles back him up) but it’s usually The Fab Four that get all the credit.
