5000 Volts is the name of a British disco recording act that achieved success throughout Europe during the 1970s. The group consisted of vocalists Tina Charles and Martin Jay, with a changing group of session musicians. 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. Members: Linda Kelly Martin Jay Martin Cohen Kevin Wells Mike Nelson. 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.
