The Beatles: Paul McCartney was stunned by vulgar message implanted in Sgt Peppers

Paul said: “Some fans came around to my door giggling. They said: ‘Is it true, that bit at the end? Is it true? It says we’ll f**k you like supermen.’ 

“I said: ‘No, you’re kidding! I haven’t heard it, but I’ll play it.’”

He recalled going to find out the truth about the song, adding: “I went inside after I’d seen them and played it studiously, turned it backwards with my thumb against the motor, turned the motor off and did it backwards.

“And there it was, sure as anything, plain as anything. ‘We’ll f**k you like supermen.’ I thought, Jesus, what can you do?”
