You knew it was only a matter of time: Karate Kid: The Musical. (Seems like its engagement has already run, but there's some music available for download.)
Anyone that knows me knows that musicals really aren't my bag, baby. There are a few that I like: South Pacific, Guys and Dolls, The Rocky Horror Picture Show, and Little Shop of Horrors. Those have some really catchy songs. Something about all the characters breaking out into song just seems cheesy, though. But with lyrics like this, I think that I can tolerate it:
I'm the evil sensei
It's my evil dojo
I teach evil karate
I'm evil as a mofo
Oh, and there's also a Silence of the Lambs musical.
