Because they both have sound tracks. Okay, enough of the corny riddles. It's just my way of asking if anyone else here is into 1960s-70s TV and movie soundtracks. I was delighted to find that someone has finally released 1966's "Batman" as a soundtrack CD. Nelson Riddle's music has never (AFAIK) been released in its original form, despite its wide popularity. So it was great to finally find it. I ordered and received my copy recently, and it's a wonderfully jazzy score. A lot of times the hard-to-find ones are the best. The movie "Casino Royale" has a very catchy, loopy soundtrack, and it's out on CD. So are the musical tracks of Lost in Space, The Time Tunnel, and other Irwin Allen TV series, many of which were composed by a young John Williams. Gerry Anderson's UFO and Space: 1999 and Patrick McGoohan's The Prisoner are out there, as well as Dan Curtis' "The Night Stalker" and "House of Dark Shadows". All I can say is, thank God for our interest in all things retro and nostalgia! I'm finally building up a nice collection of music I've wanted for, oh, thirty years or so.
