Hahaha...well you're attempting, which in itself can be very rewarding, even through failure.
Have you studied music in school at all (writing, notes, instruments, tecnicalities, etc.)? I never did, which lends to my inability to write anything.
I have a few friends who have, so I figure that I could just bounce things off of them if anything ever got off the ground.
By the way, have you found anything yet along the lines of evangelistic or christian-based musicals? I would be very curious in reading something like that.
I was in a musical when I was young once and it was about representives from different states coming together and talking about how God and the founding fathers had made this nation (America) great. It was an Independance Day musical that a church I had gone to did. More just a medley of songs than an actual musical from what I remember.
I also saw a rock opera at a christian music festival I went to the summer before this past one. It was about a woodsman giving his life to save his daughter from an evil prince or something. I don't remember it fully (mostly because I got there after it had started) but it parralled the story of Christ's sacrifice for us, his children. The group that put it on was called Divebomb or Divebomber...I know they have a website. *shrug* I suppose if you're looking they might be a place to ask questions.
