Broke down and got the complete Buck Rogers TV DVD set today. Chalked it up to an early birthday present. Skimmed the pilot movie, which is the only one that has the lyrics to the theme song. And I'm goober enough to transcribe them and bring them to you.
First, you know the premise: 1987 NASA releases the last deep space probe (which looks like a space shuttle launched by an Apollo rocket. Hey, they didn't have the stock footage yet) Accident, bam, gets frozen. Then William Conrad says "For 500 years Buck Rogers drifted through a world in which reality and fantasy merged into a timeless dream..." And atop the Buck Rogers logo is our hero sleeping when he isn't making out with Space Disco babes, we are treated to the following:
Far beyond the world I've known
Far beyond my time
What am I
Who am I
What will I be
Where am I going
And what will I see

Searching my mind for some truths to reveal
What thoughts are fantasy
What memory's real

Long before this life of mine
Long before this time
What was there
Who cared
To make it begin
Is it forever
Or will it all end

Searching my past for the thing that I've seen
Is it my life or just something I've dreamed

Far beyond this world I've known
Far beyond my time
What kind of world am I going to find
Will it be real or just all in my mind
What am I
Who am I
What will I be
Where am I going
And what will I see

Hey, it beats Roddenberry's lyrics for Star Trek.
