A Los Angeles vocal trio, the Hues Corporation enjoyed two big hits in the mid-'70s, notably "Rock the Boat" in 1974 for RCA. While it was lightweight, mainly pop work, it did take The Hues Corporation to number two on the R&B charts and get them their lone pop chart topper. The next single, "Rockin' Soul," peaked at number six on the R&B charts and number 18 on the pop charts. They had their final R&B hit the next year with "Love Corporation," which reached number 15, but it was evident that the audience was losing interest in their material. "I Caught Your Act" was the last release in 1977. H. Ann Kelley, Flemming Williams, and Bernard "St. Clair Lee" Henderson were the original lineup. Tom Brown replaced Williams in the wake of "Rock the Boat's" success. He was then replaced by Karl Russell in 1975.
