Jamaican vocal duo formed by Bob Andy (real name Keith Anderson) and Marcia Griffiths, who was also a member of the I Threes backing Bob Marley. The duet reach #5 UK hit single in 1970 with their cover of Nina Simone's Young, Gifted And Black and a minor hit in 1971 with Pied Piper. They discontinued their partnership in the mid-1970s, both feeling that it was not bringing them adequate financial reward.
