Tripping The Light Fantastic - a new musical by the authors of The Desert Peach Musical: http://ping.fm/GHQuB
We really learned our lesson on this one. The actors, male and female, can wear their street clothes. Except for the crazy spiritual lady, but the costumer can trot down to the local rummage sale or a couple garage sales and put together a sparkly version of a hippie costume.
The props people can get the furniture from St. Vinnie's and pick up the scrap lumber while they're there.
Any budget can be blown on cool glittery light effects -- and if all you want to do is get a mirror ball and some lasers, you can do that, too.
This one's about the music and the lyrics and the singers. All stuff that's going to sound really good on itunes!
