This is a question that I started to consider when I was informed that Sondheim has never had a show run more than 1000 performances on Broadway. So that made me think about who has had the most.
The first person I thought was Andrew Lloyd Webber, but at a quick glance I only count three, Evita, Cats, and Phantom (although I didn't look at all of his shows, only the ones I knew were successful)
My second was Harvey Fierstein, who has had Newsies, La Cage, Torch Song Trilogy, and Kinky Boots all run over 1000 (plus Hairspray, which he ghostwrote but he isn't credited as a writer on)
Does anybody know of any book writer, composer, or lyricist who can lay claim to more than 4 or 5 shows that ran more than 1000 performances on Broadway?
