Although I don't remember the theme song I always watched Rocketship 7 and Commander Tom. It was funny that the show lasted till 1978, I can't remember when I started getting too old for it.
I remember the call in game where the lucky caller had to pick a planet, behind the planet was the prize for the caller. As I recall, most of the prizes were lame gift certificates but every once in a while there would be a bike or cool prize. Once I remember a girl got to be the lucky caller, she picked her planet and got a boys gift,(like a race set or something), Captain Dave was trying to ask if she had a brother or something, and she hung up.
On sick days I would get to stay home and watch Nolan Johanes on "Dialing for Dollars", also a classic!
