Where is Dan Bredemann's play, "I Am Not Lewis Carroll"?

In the 90s, Dan Bredemann showed me a copy of his one-man play, I Am Not Lewis Carroll. It was about the inner life of the fantasy author and logician Charles Dodgson, who is better known under his pen name, Lewis Carroll. I had time during my visit to read only a few parts, and he died in 2005. I’ve been wanting for years to read the whole play, but have not found it in published form. Still, it’s hard to believe that it has vanished altogether. Is a copy to be found anywhere, published or unpublished?
