GUEST,Steve Zodiac - a very vague (and embarassing memory) thinks it should be 'Venus of the stars'

(This is Fireball XL5 by Gerry Anderson for the uninitiated, a puppet series from UK TV in the late 60s - I think. Steve Zodiac was the daring space pilot, Venus was his suitably blonde partner and Fireball was the rocket ship. Anderson went on to make Stingray, Joe 90, Thunderbirds and many others)

And I seem to recall the lyrics went something like

I wish I was a spaceman/The fastest guy alive/I'd fly around the universe/In Fireball XL5/Way out in space together/Conquerors(???) of the stars/ My heart would be a fireball/A fireball/And you would be my Venus of the stars Oh I'm SO embarrassed......

And then there was another verse about Milky Way and Mars....... urgh!
