There were two versions of the song available. The 7" version would later become the "album version", as it would eventually appear on the UK version of Speak & Spell, released in October 1981, and a 12" "remix," which differs from the "album version" in that it has a different intro, intensely percusive and harder, and an added synth part in the "solo" vocal section in the middle of the song, which is not present on the 7" mix. The "remix" would later appear on the US version of Speak & Spell.
