The Rubettes

The Rubettes (often referred as Rubettes since 1975) were an English pop band of the 1970s, assembled in 1973 by the songwriting team of Wayne Bickerton, the then head of A&R at Polydor Records, and his co-songwriter, Tony Waddington, after their doo-wop and 1950s American pop-influenced songs had been rejected by a number of existing acts. The band duly emerged at the tail end of the glam rock movement, wearing trademark white suits and cloth caps on stage. Their first release, "Sugar Baby Love" was an instant hit remaining at number one in the UK for four weeks in May 1974, while denting the U.S. chart at number 37 that August, and remains their best-known record. Subsequent releases would be less successful, but the band soldiered on and continued to tour on the nostalgia circuit well into the 2000s.
