アイ・アム・ザ・ウォルラス
In advance of the EP's release, Lennon promoted the soundtrack in an interview on the BBC Radio 1 show "Where It's At". Lennon discussed the studio effects used on the new songs, including "I Am the Walrus", which received its only contemporary airing on BBC radio when disco jockey Kenny Everett played it as part of the interview broadcast on 25 November 1967. Due to the lyrics' inclusion of the word "knickers", according to author John Winn, the song "remained unofficially prohibited from BBC playlists for the time being". "I Am the Walrus" was also banned from American airwaves.
