Audio tape: in '77 I "appropriated" my dad's old reel-to-reel tape recorder and recorded just about any good theme from TV I could find. It was always a bonus to get a few seconds of a game show theme without applause! I rarely recorded entire shows.
I used to love the music on Dating Game, Whew, Wheel of Fortune, Jeopardy '78, etc. Also recorded themes from other TV shows like Bewitched (back in the '70s you actually heard more than just today's standard two opening themes).
Unfortunately a lot of it is lost to time now. I still have the tapes, but my dad's machine was one of those rare 4-track machines, which meant 2 on each side of the tape. It doesn't work very well anymore and it's hard to find other reel-to-reels that will do 2 tracks on each side (most do 1 only). I did save some of it to audio cassette though.
I also loved the theme from an short-lived NBC show called America Alive. I've got 3 versions of the theme all largely without applause...but having said that, does anybody out there have clean copies of that one, by any chance? (I'm a sucker for a great melody!)
