Formed by Englishman Les Humphries in Berlin in the early '70s, the Les Humphries Singers performed a mix of gospel, R&B, pop, and rock that was not dissimilar to the work that would make Boney M European superstars. The group's biggest hits were the singles "Mexico" and "Mama Loo," released in 1972 and 1973 respectively. The ensemble also represented Germany at the 1976 Eurovision Song Contest, but was to break up soon after. A reunion occurred in 1991, but only lasted a couple of years. 2006 would see many of the original members -- sans Les Humphries -- return as the Original Singers. Other members of the Les Humphries Singers also went on to success in their own right, with Liz Mitchell going on to front Boney M, and John Lawton finding a home as the frontman for Uriah Heep. Humphries himself passed away in December of 2007.
