Gaynor was a singer with the Soul Satisfiers, a jazz/R&B music band, in the 1960s. She recorded “She’ll Be Sorry/Let Me Go Baby” (for the first time as Gloria Gaynor) in 1965, for Johnny Nash’s Jocida label. Her first real success came in 1975 when she was signed to Columbia Records by Clive Davis. The fruit of that was the release of her album Never Can Say Goodbye on Columbia Records. The first side of the album consisted of three songs (“Honey Bee”, “Never Can Say Goodbye” and “Reach Out, I’ll Be There“) with no break between the songs. This 19-minute dance marathon proved to be enormously popular, especially at dance clubs. All three songs were released as singles via radio edits and all of them became hits. The album was instrumental in introducing disco music to the public, “Never Can Say Goodbye” becoming the first song to top Billboard magazine’s dance chart. It was also a hit on the mainstream Pop Charts, peaking at #9, and on the R&B Charts, reaching #34 (the original version by The Jackson 5 had been a #2 hit on the Hot 100 in 1971). It also marked her first significant chart success internationally, making it into the Top 5 in Australia, Canada, Germany and the UK. The song would go on to be certified silver by the British Phonographic Industry, and subsequently gold in the US.
Capitalizing on the success of her first album, she quickly released her second album, Experience Gloria Gaynor, later that same year. Some of her lesser-known singles, due to lack of recurrent airplay — including “Honey Bee” (1974), “Casanova Brown” (1975), and “Let’s Make A Deal” (1976), as well as her cover of The Four Tops‘ “Reach Out, I’ll Be There” (which also became a #14 hit on the UK Singles Chart) — became hits in the clubs and reached the Top 5 on Billboard‘s disco charts. Many charted on the Hot 100 and R&B charts as well, with songs like “(If You Want It) Do It Yourself” – a #1 disco hit – peaking at #98 on the Pop Charts and #24 on the R&B Charts. Her cover of “How High The Moon” topped the US Dance Charts, and made the lower parts of both the Pop and R&B charts, as well as achieving some international chart success. After her 1976 album, I’ve Got You, she shifted from her hit production team, to work with other productions. Gaynor has recorded some 16 albums since, including one in England, one in Germany, and two in Italy.
