HOT TICKET: Even if you didn’t get a ticket to the annual Warren Haynes Christmas Jam, which sells out every year, there’s plenty of live music to be heard during the daytime programs. The songwriter-oriented Kevn Kinney Jam takes over Jack of the Wood Friday and Saturday. “You end up staying there pretty much all day,” says Leigh Glass, who will perform with her husband, Corey Bullman. “It’s packed every year, and it’s great.”
