TOD:
I'm not even sure that it counts, but Smokey Joe's Cafe is just about the only jukebox musical that works for me: rather than shoehorning the songs around the plot, the writers simply played the show as more of a revue, allowing the songs themselves to suggest their dramatic nature.
I would have loved to see what Harry Chapin would have done with his "Last Protest Singer" project, although I suspect that it wouldn't have gone too far.
Other musicians whose work I'd love to see staged in some form: Rush (I can't be the ONLY person who wants to see someone do "2112" on stage, can I? Okay, maybe I can), Pete Seeger.
And I can't believe that I'm going to admit this in public, but I bet you could make a pretty good staging from Madonna's catalog... (as the last two people on earth who believed that I was straight slink away shaking their heads)
