Help me pick which show to see - parents are in town visiting: Book of Mormon, Choir of Man, or Six!

Hi all my parents are in town from Canada and I’m looking to book us all tickets to a play — thinking either of the 3 above but also open to other ideas. I’ve seen Book of Mormon years ago so I know they would enjoy it but they want to see something ideally I haven’t watched yet, so that’s why I’m thinking either choir of man or six. I want something fun, funny and good time. I heard Six! Is super short so I don’t love that. It’s also October so maybe Stranger Things or something spooky would be fun. Pls let me know your thoughts!
