SHY is dishy, sure, but it’s also incredibly moving. I think it’s more than a “Broadway” book, despite being written by (or dictated by) a Broadway Brahmin.
EVERYTHING WAS POSSIBLE, too, is an even tempered, pretty journalistic book. Dish? I suppose, but it’s not bitchy. But I agree— one of the best theatre books ever.
Ken Mandelbaum’s book on Michael Bennett is sort of dishy, but very informative, too. Kevin Kelly’s is utter trash, though I have begun to believe there’s enough truth in it than untruths.
