[musicals] I started singing randomly the other day, what is going on?

I'm a banana vendor in New York City. The other day some girl came down the street singing about love lost, or missing her honey at the big dance or some crap like that. Suddenly I had the overwhelming urge to sing along with her, or more like be here backing singer. I swear I even heard an orchestra. Am I going crazy? Was she some sort if witch ?

There's a demon named Sweet in your town.  If you're lucky the Slayer will deal with it.  If you're not, you'll eventually take part in increasing number of musical incidents and will finally dance until you burst into flames.  

Good luck!
