I don't feel like playing this list game but I do want to include ...
Phil Manzenera (Roxy Music / 801)
Oh yeah, and Dupek, wasn't John Goodsall one of those often session players or with Godley and Cream or Soft Machine or Matching Mole or Brand X? I can't remember and don't feel like researching now. I definitely know his name from some earlier works. Might have worked with Brian Eno or King Crimson.
