Mervyn "Spam" Spence (born 1958) is a Northern Irish musician and producer, best known for his work with Wishbone Ash and Trapeze.
Spence moved to Staffordshire from Ireland in the late 1970s, and began playing with bands such as The Jury and Big Daisy.
Spence briefly toured with the band, and during his tenure recorded one album's worth of material, which – due to Galley's departure to replace Bernie Marsden in Whitesnake – remains unreleased.
[1] Several of the songs from these sessions however (Demos exist in bootleg form), would form a very small part of Tom Galley's Phenomena project, which Spence would later join to sing and play bass on the 1992 album "Innervision" (billed as "O'Ryan") Spence later went on to buy the rights to the project, cashing in (and dining out) with a 'best of' compilation which featured a very small percentage of his work tagged onto the work of the real members of the project.
Following the break-up of Trapeze, Spence was offered an audition for Wishbone Ash while he was pitching demo material to various outlets.
