I remember being surprised to see Cy in an episode of Blakes 7 back in 1980 playing the father of Dayna Mellanby, who became a regular member of the crew. It had been some years since I'd seen him on TV singing and didn't know he was an actor, but looking into it I see he also voiced Lt Green in Captain Scarlet and the Mysterons amongst other things.

Glad to hear he's still with us.
