"Substitute" by Clout

Clout was an all-girl pop group from South Africa who put their ABBA-like spin on a number of tunes in the 70s. Among some of the artists they've covered are Hall and Oates, Eric Clapton, and Russ Ballard (Argent).

Clout's songs populated the charts throughout the world until they broke up in 1981, but here in the US they barely became one-hit wonders with their excellent rendition of "Substitute", originally performed by The Righteous Brothers. Clout's version got to #67.
