I was wondering about how many records feature Billy Currie,
As far as I know a possible discography should sound like this (apart from FoxxVox and Urevox albums & singles). This is just an aide memoire and not a proper and detailed discography.
Any addition or info will be welcomed:

Billy Currie Transportation lp/cd/tape
Billy Currie Stand Up and Walk cd (lp? tape?)
Billy Currie Unearthed cd
Billy Currie Keys and the Fiddle cd

Gary Numan The Pleasure Principle lp/cd/tape
Gary Numan Living Ornaments 1979 (live) lp/cd/tape

Visage Visage lp/cd/tape
Visage The Anvil lp/cd/tape
Visage Fade To Grey-The Singles Collection (also dance mix version) lp/cd/tape
Visage Beat Boy lp/tape

Ultravox Revelation lp/cd/tape
Ultravox Ingenuity cd
Ultravox Future Picture cd

The Armoury Show Waiting For The Flood lp/cd/tape

Steve Howe Turbulence lp/cd/tape

Duffo Gonna Send The Boys Around 12"

VV.AA. Freispiel (german cd with a Billy Currie unreleased solo track) cd-only
