Also, Gypsy, Sweet Charity, and Hair.
And we're getting a little technical here, but Porgy and Bess, On Your Toes, Anything Goes, Carousel, Show Boat, and Annie Get Your Gun won Best Revival but did not win Best Musical because the Tonys weren't around yet.
And, of course, Assassins, which won Revival but the original production was off-Broadway.
