How do you define long-running. Hamilton has only run about 1,400 performances. Until maybe 20 years ago, we never had long-runs like today. Too broad a question.

Good point. Does the OP consider something like "Book Of Mormon" also. My answer is going to reflect a show that ran at least 10 years and say "Les Miserables".
