Well I have a Doctor Who eppisode with Peter W in it from the 70's but let me have a think ..
Oh and another thing - Peter is also in a few of the ITC productions .. I have a collection of DVD of
The Saint, Danger Man, The Baron etc and I have seen him in - I think it was The Baron.
He also has done a audio comentary of sorts for the Department-S DVD box set that I purchased - so he's still around- I think living quietly in London.
I remember he had a spot of trouble in the early seventies which put a dampner of his career for a little while.
Anyway - back to your question Jonatham .. umm .. can I cheat ??
Let me rush to the other room and check something
(I have the Peter Wyngarde CD album ..maybe the liner notes will enlighten me..)
Uh Huh!! I have it ... "Flash Gordon" (1980) .... Klytus
