The Hues Corporation was a pop and soul trio formed at Santa Monica, California in 1969. They are best known for their 1974 hit, "Rock the Boat". The group's first big break came in 1972 when they were invited to appear in the blaxploitation film, Blacula, starring William Marshall. They were also asked to record three songs for the film's soundtrack; "There He Is Again", "What The World Knows" and "I'm Gonna Catch You". Shortly after, RCA signed the group and their first single, "Freedom For The Stallion", from the album of the same name, became a moderate hit, reaching #63 on the Billboard Hot 100 chart. The follow-up single, "Rock the Boat," became a #1 hit on the Billboard chart and the group's signature song. The track sold well over two million copies.
