"Ladies Who Lunch" is definitely COMPANY's 11 o'clock number, "Being Alive" comes too late in the show. An 11 o'clock number is not necessarily the finale or the last song.
"Lot's Wife" is the best in recent memory, IMO.
"Sit Down You're Rockin' the Boat" (not "Marry the Man Today"), "Rose's Turn," "The Miller's Son," and "I'm a Brass Band" are some classic 11 o'clock numbers.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
