The Beatles often hid references to drugs and sex in many of their songs. However, most of the band’s music is relatively clean in terms of profanity and swear words. Still, The Beatles were creative in hiding their provocative references, and Paul McCartney reveals the Fab Four managed to hide a curse word within the lyrics of their song, “Sun King.”The Beatles made up some words and phrases for their songs, such as “Goo goo g’joob” in “I Am the Walrus” and “Ob-La-Di, Ob-La-Da.” However, the band mixed actual words from other languages in “Sun King,” a song from Abbey Road. The final group of lyrics contain words from Italian, Spanish, and Portuguese. In a 1969 John Lennon interview (shared by Beatlesbible.com), Lennon shared how he and McCartney came up with the blend of languages.
