[Musicals] I was just working in my bar when a large group of people ran into my place, started singing and dancing all over the tables and throwing stuff to each other, stole my hat and ran out again.

They've caused absolute chaos all over town. They're dancing on top of cars in traffic, swinging on lampposts, causing significant vandalism and bringing the whole area to a complete standstill. From information I've gathered, the leader of this group of roaming troubadours had just gotten engaged so had to sing a jaunty number and the rest of the people had just gotten caught up the the group.

Now that I think about it, this happens a lot. A LOT. Random masses of very well choreographed people holding up entire streets, shops, homes and parks are everywhere and seem completely spontaneous despite looking like they've practiced for weeks with music that plays from seemingly nowhere.

I want to know who I charge for the damage to my bar. They've made a huge mess, taken my stuff and caused a lot of damage. Will my insurance cover roving hordes of dancers? And how do I get this to stop? Are the laws deciding who is allowed to lead these singing troupes?  What circumstances warrant these routines? If I cook a cracking roast, run into the street and sing an impromptu song, will other join in or will I look like a crazy person?

Your insurance doesn't cover it. 

Best bet is to start working while singing a catchy tune. With luck, others will pick it up. Soon you'll have a whole horde of surprisingly well choreographed builders arrive and do several hours repair work in about 3 minutes.
