Yale Cabaret.

The Yale Cabaret was established in 1968 in the old Phi Gamma Alpha fraternity house (217 Park Street) as a coffee shop with the purpose of doing "experimental work" and providing a space for guest artists, faculty, and students to perform. On November 8, 1968, the Cabaret opened its doors with its first performance by Alvin Epstein and Martha Schlamme, singing the songs of Kurt Weill.
