They released several singles in the mid-1970s, but did not achieve success until radio stations began playing the B-side to their 1975 single, "Bye Love". The song, "I'm on Fire", was released in its own right and became a major hit throughout Europe, peaking at number 4 on the UK Singles Chart;and at number 1 on the German Top100 Singles chart and the Swedish chart and also number 10 in South Africa. It was also a major top 10 hit in Australia and charted in the United States where it reached number 26, heavily struggling against Jim Gilstrap's version of the song which hit #78. Although Tina Charles provided the vocals, she was not publicly acknowledged as the group's singer and for the band's 1975 appearance on BBC Television's Top of the Pops they were fronted by singer/actress Luan Peters (best remembered for her role as Raylene Miles, an Australian tourist in an episode of Fawlty Towers), first broadcast in 1979. In 1975 the group was expanded by record producer Tony Eyers into a permanent five piece, with the inclusion of Martin Cohen (bass and vocals), Kevin Wells (drums) and Mike Nelson (keyboards). Subsequent singles failed to attract widespread interest in the UK, although the group became popular in South Africa and Germany. Charles left the group after a dispute with the record label and continued with her solo career. She was replaced by Linda Kelly. The next single "Doctor Kiss Kiss" reached number 8 in the UK, and number 6 in South Africa, but the band struggled to maintain public interest. The group disbanded in 1978. Martin Jay launched a solo career without success, before returning to his earlier role as a session musician, working for bands such as Enigma, Tight Fit in 1981 and the UK Mixmasters in 1990. In 2012 Tina Charles and Martin Jay re-united to record some of their hits as well as some well known classics. The album 'Reunited' was the result of their reunion.
