The Winter Solstice (December 21 this year) is the real reason for the season. We celebrate this festive time of year with music and freethought humor, including songs and performances by Kristin Lems, Dan Barker, Tim Minchin, Roy Zimmerman, Irving Berlin, Trey Parker, Tom Lehrer, the London Humanist Choir, Ken Lonnquist and Brent Michael Davids.
