The Beatles slipped swearing on to the album Abbey Road as joke, Paul McCartney has admitted.
Among the English and schoolboy-Spanish lyrics on the song Sun King is the phrase “chica ferdy.”
Paul explained on his website that kids in Liverpool, where he grew up, would say “chica ferdy” instead of “f*** off”.
“It actually exists in the lyrics of The Beatles song ‘Sun King’.
“In that song we just kind of made up things, and we were all in on the joke. We were thinking that nobody would know what it meant, and most people would think, ‘Oh, it must be Spanish,’ or something.’
“But, we got a little seditious word in there!” He added: “When you are kids you make up silly things, and what’s great about it is you and your friends all know those silly things… So, they don’t have to mean anything!
“We had a few words and phrases that, if one of us said it, would amuse the others because it was like a secret code. But I suppose at lot of this came from The Goon Show, a comedy show on the radio.
“We just used to say absolutely silly little things.”
Abbey Road, released six months before the band’s 1970 split, was a huge hit.
