What does the conductor in the Music Man?

I auditioned for the school play we are doing, which is "The Music Man". I looked at the cast list on the Drama website and saw next to my name 'Conductor/Towns person. Its in the order of appearance, and I'm the first one on the list. I have no clue what my part is about and I really want to know: am i a boy? is it a good part? do i get a ton of lines? do i get to sing and dance?
