George Harrison was not a fan of the 1974 musical John, Paul, George, Ringo, and Bert. He hated when people ripped The Beatles off. However, sometimes, Beatles musicals and films only happened because the band didn’t look after their interests following their split.
In a 1987 interview, Creem Magazine asked George what he thought of the musical John, Paul, George, Ringo, and Bert, which debuted in Liverpool in 1974 and then made its way to London. George didn’t have anything nice to say about the musical based on The Beatles.
“I saw it up until the intermission and then–I saw it with my friend Derek Taylor, who’s a writer who used to work for Warner Bros. and Apple–I said to him we either have to leave now or I’m gonna jump on that stage and throttle those people,” George said.
