Songs for the Cause: A Tribute to Activism and the Lincoln Brigade with Pete Seeger + Patti Smith + Guy Davis and more

Pete Seeger is 91 years old and still hasn't learned how to say no to charity gigs. The man's a mensch! Tonight he leads Patti Smith—for the first time in years, on a bill with someone old enough to be her father—and singer-songwriter Guy Davis to raise funds for the Abraham Lincoln Brigade Archives.
