ASK BK ?
Did you cast your musical recordings like Night of the Hunter, Colette Collage, Drat! The Cat! and others like you'd cast the theater version?
Finally, a question. I refuse to answer!!! Only kidding.
NOTH and CC were cast collaboratively with the authors - but, yes, everyone on those recordings were perfect for their roles and the show.
Drat, I cast myself, as it was my baby. I do think everyone on the recording could do the show, with the exception of Elaine Stritch, who wasn't really right for her role, but who we wanted for her talent and name value.
