Closing song for cabaret help!

Hello! I am putting together a virtual cabaret that features all songs from historical musicals. I would like to have a group closing number and I cannot think of a good one. The closing number doesnt have to be from a historical musical but I wanted to like some up what were doing with the historical musicals? If that makes sense? It also doesnt have to be written as a group number but if Kimmie song as a group number that would be fine. Any ideas? Thanks in advance!

So just for clarification, are there any major themes for the cabaret that are shared between songs? And when you say “historical” do you mean major musicals, or musicals about historical events?
