One early success story was the Tarney-Spencer Band's single, "No Time to Lose." Australians Alan Tarney (guitars, vocals) and Trevor Spencer (drums) rose to prominence as members of Cliff Richard's backing group in the early 1970's, and went out on their own in 1975. They released three LPs, the last one being 1979's Run For Your Life. The album was a modest success, reaching #184 in the U.S., while the single "No Time To Lose" peaked at #84. Soon afterwards, A&M dropped the band, and the duo broke up.
MTV picked up the "No Time To Lose" video (roller skates and all) in 1981, and a re-released version of the single reached #74 on the charts -- 2 years after the group broke up. Unfortunately, Tarney and Spencer had moved on with their careers, and no attempt was made to reunite as far as I know.
Interestingly, both Alan Tarney and Trevor Spencer would go on to become producers, and remain in the industry to the present day. Trevor Spencer moved back to Australia and is a Perth-based producer, while Alan Tarney remained in the U.K. Tarney is best known for his work with a-Ha -- he co-produced the band's first three LPs, including Hunting High and Low (which included the huge hit, "Take On Me.")
