10 Hard Rock Bands That Made The Same Song Twice

Given the length of their career, Black Sabbath did a fine job of consistently producing fresh material, stacking up hits and rarely revisiting old tracks outside of live performances. And the reason for this may have something to do with their extensive line-up changes, especially where vocalists are concerned.

Ozzy got the boot in the late-'70s and, far from revisiting his material with Dio, the band turned over a new leaf, found a new sound and steamed ahead. This was the case time and again over the years, giving each of the group's eras their own distinctive feel.

However, that didn't prevent overlap, as, although Sabbath are best known for their long-term line-ups, they released more singers than albums in the mid-'80s. Enter Black Moon, a single written during Ray Gillen's tenure, but which his replacement Tony Martin did vocals for. The first version was a B-side for a single from The Eternal Idol (1987), with Martin's vocals tracked too late for inclusion on the album. Thus, a proper, rerecorded version appeared on 1989's Headless Cross.

Strangely enough though, the rerecording sounds considerably less professional than the original, with the excessive reverb and raw drums you might expect to hear on a demo. In any case, neither version has become a Sabbath standard, begging the question of whether it was worth doing at all.
