|Members of the Princeton University Tigressions carol at the
"Holiday A Capella Jam" on the Palmer Square Green. The all-female
chorus was founded in 1981 by a group of Princeton undergraduate women
intent on adding a feminine timbre to the university's unaccompanied
voice tradition. Amazingly, Princeton did not become a coed university
until 1969. Several a cappella groups participate in the annual jam as
well as the Princeton University Band. There is free hot cocoa, apple
cider and magic for all.
