"Desperate But Not Serious" was the third single and music video from Adam Ant's first solo album, Friend or Foe. and was released on 19 November 1982. It peaked at number 33 on the UK Singles Chart, and number 66 on the Billboard Hot 100 in the US. Both the studio version and a live version of "Desperate But Not Serious" appear on the double Adam Ant compilation, Antmusic: The Very Best of Adam Ant.

"Desperate But Not Serious" was written by Adam Ant and Marco Pirroni. The track features Adam on vocals and bass guitar, Marco on guitar, Geoff Daly on saxophone, Martin Drover on trumpet and Bogdan Wiczling on drums.

It was fairly common for Ant to record new versions of his pre-1980 compositions for the B-side of his singles. For this single, an old Ant song from 1978 called "Why Do Girls Love Horses?" was used. Ant first recorded the song as a four track home demo in July 1978 while living in Notting Hill Gate. The song remained unused until this particular version was recorded in 1982. The song finally received its live debut in December 2010 at a concert at Camden's Electric Ballroom as part of Ant's World Tour of London 2010-2011.
