Before scaling the hard rock heights with Rainbow and Alcatrazz, Graham Bonnet belted out contemporary covers with his cousin, Trevor Gordon, in the Marbles. Born in Lincolnshire, England, Bonnet performed with a blues band and a jazz trio before hooking up with Gordon, who played with the Bee Gees, and the Marbles caught the interest of media mogul Robert Stigwood at RSO Records. The first Marbles single, "Only One Woman," a Gibb brothers composition, did well in the U.K. and Australia. Another Gibb tune, "The Walls Fell Down," also received airplay, but the Marbles abruptly broke up. Transitory behavior would become typical of Bonnet's career. Though the band split, the eponymous Marbles debut dropped in 1970. ~ Whitney Z. Gomes, Rovi
