"What Is Love?" was the 2nd single by musician Howard Jones. Released in November 1983, from the album Human's Lib, it reached number 2 in the UK Singles Chart, becoming the singer's highest chart placing to date. In the US it peaked at #33 on the Billboard Hot 100 chart during the summer of 1984.
The song was originally entitled "Love?" on the demo tape (listing below) which Howard Jones recorded in 1982, which itself was available at his gigs. Howard Jones also used the question mark motif around this time on posters advertising his gigs; posters which also hung behind him on stage at his early 1980s Marquee Club appearances and which read simply "Howard Jones?".
The song was used in the 1984 film Supergirl
