The Beatles are arguably the greatest rock band of all time. Although in this case, the word "arguably" is only being used because, technically, someone could argue against it. But, most likely, that person would lose that argument.
The biggest hit from the biggest band was their 1968 classic "Hey Jude." It spent nine weeks on the top of the U.S. chart, and also topped the U.K. chart. And the song is unusually long for its era, clocking in at over seven minutes.
A lot can happen in a song if it lasts for seven minutes. This is true for "Hey Jude," even though the last half of the song mostly contains repetitions of the syllable "Na." In fact, in one part of the song, there's a barely-audible F-bomb.
Emerick said, "Right between the lines 'The minute you let her under your skin/ Oh, then you begin' you can clearly hear Paul curse off mic saying 'F****** hell!'" He explained that Paul said it after playing the wrong note on the piano.
Of course, Emerick could have edited the curse out of the final recording. However, John Lennon told him to leave it on. He said it would be so quiet in the final mix that nobody would know it was there. Nobody except The Beatles.
According to Lewisohn, Lennon was at the part of the song where he was supposed to say, "Let her under your skin." But instead he started singing, "Let her into." Realizing he sang the wrong part of the song, he let the expletive fly.
However, The Beatles aren't the only band to drop the F-bomb into a song. For instance, the song "Louie, Louie" was famously investigated for supposedly raunchy lyrics that weren't really raunchy after all. But, like in "Hey Jude," it has a barely-audible accidental F-bomb at the 0:53 mark.
The Who also got the F-word into a song that gets played on the radio all the time. But in this case, it's very audible and not accidental at all. At the 2:05 mark, Roger Daultrey is heard clearly shouting, "Who the F*** are you?"
R.E.M. were known for having great songs...and for it being hard to understand exactly what singer Michael Stipe was saying. That's probably why the F-word at the end of this song was able to sneak onto the radio. Near the end, you can hear him sing the words, "I never understood, don't f*** with me."
