Just found a copy of Arthur's book from '09 "Mainly on Directing" at the rapidly dwindling Borders here. He finally devotes a whole chapter to "La Cage" called "Smoke and Mirrors". To hear him tell it, it was quite the lovefest when he, Jerry Herman and Harvey Fierstein started work on the show, and continued as a lovefest throughout the rehearsal period, the Boston tryout and into New York. Funny, if his dealings with Harvey are what he called a lovefest, I'd hate to have seen what he called a bitchier environment. Be curious to hear Harvey's recollections one day in a memoir.
No big event at some Broadway theater where people pretend to be sad and respectful, all the while delivering barbed eulogies they've been practicing in the shower for years:
"Arthur and I were the best of friends for many years until one day when..."
