Mbo, I know what you mean about missing a second home when you're back where you thought you always wanted to be. When I visit Denver now, I find myself thinking of Boston. But "Charlie on the MTA" doesn't make me homesick. I'll have to think about what song means "Boston" to me.

There are songs I can't sing without crying if I'm alone, but I can sing in front of an audience. "Mama, Hey Mama" from the play 1776 is one.
