For Your Next Adventure

The party enters the tavern. In the back sits a man with a sword and a man with a crown. Upon closer examination, he appears to be the king's brother. Suddenly, he rises and yells "Everyone! I'm going to kill my brother! Drinks are on me!"

Then just play this. Or if you're really hardcore, sing it.

Gods I loved Galavant

Do the players follow? Do they start singing along? Do they sneak off and tell the king? Do they graciously accept the booze and look forward to the regime change/ execution tomorrow?
