I saw that and was even more fascinated by Furth’s bio. Especially how his early Broadway career overlapped with the leaving the Army. Then jumping to Hollywood where it appears during his filming activities he begins to write the short stories that would eventually become Company/Twigs. I find not only his bio, but his two careers on opposite coasts occurring really fascinating.
I just found another interesting link about Furth, Mary Rodgers, Prince and Sondheim.
