The best thing about the short-lived 2000 Bruce Campbell TV series Jack of All Trades is the main title theme song. Really! It was nominated for an Emmy and only lost because it was up against The West Wing. (But composer Joe LoDuca landed on his feet. He's working on Leverage these days.)
Hear the genius for yourself:
D and I have been re-watching Pinky and the Brain recently, which also has a great theme song. This is one thing I miss about modern TV shows. I blame Frasier for starting the trend and shows like Lost for exacerbating it (though the latter did make for a nice comedy bit at this year's Emmys).
I mean, if ever there was a show crying out for a theme song, it's Glee. Come on, guys. SRSLY.
Writer Lee Goldberg does a TV Main Title of the Week feature on his blog, and it's worth subscribing to his feed just to see these. They're not all good--quite a few are real clunkers--but as my friend Brian says, the main titles should tell you what to expect from the show itself. A good theme song should tell you, in about a minute, whether or not you are the audience for that show, and if you are, should make you want to go watch it immedately.
Here's a perfect example:
I rest my case.
