Which bassist played on Black Sabbath's Headless Cross album?

Laurence Cottle played bass on Black Sabbath’s Headless Cross album.

Released in 1989, Headless Cross was Black Sabbath’s fourteenth studio album and featured singer Tony Martin and drummer Cozy Powell. Laurence Cottle performed as the record’s session bassist, making him the only bassist credited on a Black Sabbath studio album without being a permanent member of the band.

Cottle was an experienced British session musician rather than a long-term Sabbath member. His playing provided the low-end foundation for an album built around Tony Iommi’s guitar work, Martin’s powerful vocals, and Powell’s forceful drumming. Brian May also contributed a guitar solo to the track “When Death Calls.”

The distractors reflect real Sabbath history, which makes this question tricky. Craig Gruber played with the band during the 1970s, Dave Spitz was the bassist on some mid-1980s releases, and Neil Murray became associated with the group around the Headless Cross era. However, the album’s credited session bassist was specifically Cottle. The original album was recorded in England during 1988 and released internationally on 17 April 1989.
