<P> "Lucy in the Sky with Diamonds" is a song credited to Lennon--McCartney that appears on the Beatles' 1967 album Sgt . Pepper's Lonely Hearts Club Band . It was started by John Lennon, then Paul McCartney contributed to it in a songwriting session . Lennon's son Julian inspired the song with a nursery school drawing he called "Lucy--in the sky with diamonds". Shortly after the song's release, speculation arose that the first letter of each of the title nouns intentionally spelled "LSD". Lennon consistently denied this, insisting the song's fantastical imagery was inspired by Lewis Carroll's Alice in Wonderland books, a claim repeatedly confirmed by Paul McCartney . </P> <P> Despite persistent rumours, the song was never officially banned by the BBC, and aired contemporaneously on BBC Radio at least once, on 20 May 1967 . </P> <P> Most of the song is in simple triple metre (3 4 time), but the chorus is in 4 4 time . The song modulates between musical keys, using the key of A major for verses, B ♭ major for the pre-chorus, and G major for the chorus . It is sung by Lennon over an increasingly complicated underlying arrangement which features a tamboura, played by George Harrison, lead electric guitar put through a Leslie speaker, played by Harrison, and a counter melody on Lowrey organ played by McCartney and taped with a special organ stop sounding "not unlike a celeste". Session tapes from the initial 1 March 1967 recording of this song reveal Lennon originally sang the line "Cellophane flowers of yellow and green" as a broken phrase, but McCartney suggested that he sing it more fluidly to improve the song . </P> <P> Lennon's inspiration for the song came when his son, Julian, showed him a nursery school drawing he called "Lucy--in the Sky with Diamonds", depicting his classmate Lucy O'Donnell (later Lucy Vodden). Julian Lennon said, "I don't know why I called it that or why it stood out from all my other drawings, but I obviously had an affection for Lucy at that age . I used to show Dad everything I'd built or painted at school, and this one sparked off the idea ..." Vodden, in a BBC radio interview in 2007, said, "I remember Julian and I both doing pictures on a double - sided easel, throwing paint at each other, much to the horror of the classroom attendant...Julian had painted a picture and on that particular day his father turned up with the chauffeur to pick him up from school ." O'Donnell died in 2009 at age 46 after suffering from lupus . </P>
