As promised: Bless You, Mr. Rosewater. Alan and Howard brought several of the songs into the Lehman Engel Workshop when I was a member. (I'm sure Skip remembers more details.) I recall "Mushogi's Waltz", "Since You Came to This Town", and "Cheese Nips". I had a discussion with Howard about the latter, the first of his notorious food songs.
I had no idea that I was in the presence of greatness, that this man would jump-start the Disney Corporation before and Broadway after his tragic death at a young age. Ah what might have been!
From listening to the demos that have been released, I think Howard could have had a career as a performer as well.
During rehearsals they complained that Vonnegut kept trying to micromanage the show. (My chagrin that I was atotal pest to the director of a college show that I wrote.)
