People involved
Jack Green (vcl/msc); together with: Ritchie Blackmore (gtr); Brian Chatton (kbr); Andy Dalby (gtr); Ian Ellis (bss); Mac Poole (drm); Pete Tolson (gtr).
Jack Green had earlier played bass with Rainbow (he doesn't appear on any recordings though), during which time Blackmore and he became friends. Thus as a friendly favour, Blackmore laid down some guitar work on Green's solo album, on a track called "I Call, No Answer".
