"Lucy in the Sky with Diamonds" is a song written by John Lennon and Paul McCartney in 1967. The song released on The Beatles album Sgt. Pepper's Lonely Hearts Club Band has cause much controversy over the years when mainstream media accused The Beatles of subliminally hinting to the drug LSD in the title and song. Since the release the band has claimed that the song was really written because of a drawing produced by John Lennon's son Julian about a school mate Lucy. Julian showed his dad the drawing and telling him that the girl was "Lucy in the Sky with Diamonds". The girl Lucy was really Lucy O'Donnell born in Weybridge, Surrey, England in 1963. The songs controversy since its release, including being banned by the BBC was because of the supposed reference to the drug LSD. When the main words of the title are capitalized it is spelling (L)ucy in the (S)ky with (D)iamonds (LSD). Lennon denied the reference during an interview with Rolling Stone. Despite John Lennon's denial on June 2, 2004, McCartney told BBC that the song is, in fact, about LSD.

Most recently the supposed inspiration Lucy O'Donnell has past away on September 28th from a life long battle with Lupus.
