The eighties were a confusing time if you were a Black Sabbath fan. Between 1982 and 1990, Black Sabbath would be fronted by six different singers... in some shape or form.
The likes of David Donato and Jeff Fenholt never got past the demo and rehearsal stage. Disillusioned and abandoned by Geezer and Ward, Tony Iommi recorded a solo album with another Deep Purple man on vocals, this time Glenn Hughes.
However, record company pressure again resulted in their 1986 album, Seventh Star, being released under the Sabbath name, despite its very un-metal AOR leanings. Then Hughes got injured in a fight and the late US singer Ray Gillen had to step in.
Gillen ended up recording The Eternal Idol with the 'band' (Iommi now the only original member) but he quit before it was released. His original vocal versions survive on the bootleg circuit but the final LP release would feature British singer Tony Martin.
