My mom got the DVD box set of Buck Rogers in the 25th Century for Christmas and we watched the first two-part episode today. I remember watching the show as a kid, but I don't know whether I've ever seen the pilot. What I do know is that I was completely taken by surprise when the theme song started and the familiar tune had lyrics!
When the end credits rolled, I found out the song was sung by Kipp Lennon, who has a website with audio clips available for download. Do yourself a favor and download Suspension (Theme from Buck Rogers in the 25th Century) immediately! It is awesome.
