“Fox on the Run” is a 1975 song by the British glam rock band Sweet, first recorded in 1974. It was the first Sweet single written by the band, rather than by producers Nicky Chinn and Mike Chapman, and was their 14th single overall. The song became the best charting single in Australia in 1975, with six weeks at number one. It is about the band’s groupie. She was unnamed on purpose.
Two versions were recorded by Sweet. The original version was produced by Mike Chapman in association with Nicky Chinn on the European version of the 1974 album Desolation Boulevard. Sweet also recorded and produced a more pop-oriented rendition as a 7″ single in 1975, which is the more familiar version of the song. The 1975 single was included on the Capitol Records version of Desolation Boulevard.
“Fox” being slang for an attractive woman, the lyrics are apparently about one of the band’s groupies;Bomp! called the song “a definitive hard-rock bubblegum record” and “one of the last glitter classics”.
