The performers are not always the same. Last show I attended had a different cast member playing the part of the Mayor. You can get a bit of a different show when they swap some of the roles around. The full names of the musicians are not given for a particular show, but you can buy a DVD of the exact show you attend, which always includes some audience participation.
Im not sure. They didnt say what the names of the actors were
