I liked the story of the blind kids coming to record for you.
I worked many years at the Indiana School for the Deaf as the Purchasing Administrator.....very interesting. That is where I learned sign language, although it is signed English not the ASL that is preferred today.
When one of my plays was produced, a lady who worked in my office wanted to come and I told her unfortunately it wouldn't be signed.....so she just asked for a copy of the script.
She read it a few times and enjoyed the play.....
