Which '3-2-1 Contact' theme is your favorite?

One of my favorite TV shows as a kid had a rockin' 80s style theme, 3-2-1 Contact made science exciting.

The very first episode opens with the making of this fantastic track, but they re-cut it several times over the life of the show.

I have a hard time picking a favorite. Which is yours?

I also loved the Villa Allegre theme.
