Hughes, and drummer Dave Holland. The band had a fairly fluid line up, finally dissolving in 1994, and although they never found commercial success themselves, several members went on to join better known bands, including Deep Purple, Black Sabbath, Whitesnake, Judas Priest, and Uriah Heep.

The core and most familiar line-up of the band was Glenn Hughes, Mel Galley, and Dave Holland. After Glenn Hughes' departure in June 1973, Galley and Holland kept the band together with constantly varying members until 1979, when Holland went on to join Judas Priest. Holland tried to revive the band in 1990, after leaving Priest, but the band finally broke up in 1994. Their first three albums remain their best known and most commercially successful.
