"Sugar Baby Love", recorded in autumn 1973 and released in January 1974, is a bubblegum pop song, and the debut single of the Rubettes. Written by Wayne Bickerton and Tony Waddington and produced by Bickerton, engineered by John Mackswith at Lansdowne Recording Studios, and with lead vocals by Paul Da Vinci, "Sugar Baby Love" was the band's one and only number one single in the UK Singles Chart, spending four weeks at the top of the chart in May 1974.

Bickerton and Waddington had been writing songs together since they were both members of the Pete Best Four in Liverpool in the early 1960s. Their biggest success had been writing "Nothing but a Heartache", a US hit for The Flirtations in 1968. In the early 1970s, they came up with the idea for a rock 'n' roll musical. They co-wrote and produced a demonstration recording of "Sugar Baby Love", originally intending to submit it for the Eurovision Song Contest but instead offering it to Showaddywaddy and Carl Wayne, who both turned it down. They then offered it to the demo musicians, provided that they would become an actual group. With the exception of the recording's lead singer, Paul Da Vinci, who had signed a solo recording contract with another company, the other musicians agreed and became The Rubettes. "Sugar Baby Love" became a UK No. 1 hit in 1974, also reaching No. 37 and No. 30 on the US Billboard Hot 100 and Cashbox charts, respectively. It also reached No. 1 in Germany, Switzerland, the Netherlands, Austria, Belgium and Australia, and No. 2 in South Africa.
