The Hootie ballet

Somehow I missed this, but last year, in South Carolina, there was a Hootie ballet. A ballet, based on the songs of Hootie and the Blowfish.

You know, between this and the musicals based on Green Day and Matthew Sweet, I'm starting to wonder. Why didn't this happen to other eras of music? I don't remember an opera based on Foghat, or a stage play using only lyrics from Whitesnake songs.
