Over the years, Curtis fronted various line-ups of The Foundations, as well as appearing on his own as a solo artist. He recorded and released records on various record labels, including EMI, Opium, Pye Records, RCA Records, Riverdale, and others. In 1977 Clem Curtis and The Foundations nearly got into the Eurovision final with "Where Were You When I Needed Your Love", a John Macleod and Dave Meyers composition. They came third in the heats, and were picked as a favourite to win, but an electricians' strike ruined their chances, and "Rock Bottom" by Lynsey de Paul and Mike Moran was the winner.
