I have a copy of the demo tape. It’s just Schmidt and Jones and Liz and Scott Waara. It is a terrific, if very gentle show. There’s a terric recording of Rita Gardner singing “Time Goes By” on YouTube that will give you a taste of the show.
It’s a shame that it’s not available for stock and amateur productions.
I also have a demo of the Kander and Ebb show, which at the time was called “Over and Over”. Due to the somewhat episodic nature of the source material, the score feels like three mini musicals rather than one big show. As Kander and Ebb scores go, it’s closer to “70, Girls, 70” (which is a delight) than “Kiss of the Spider Woman”. (Actually one of Sabina’s songs was originally written for “Spider Woman” and was replaced by “Where You Are”.)
