At shows over the years we’ve acknowledged not only Hanukkah, but Easter, Passover, Halloween, Christmas . . . we even performed “Turning Japanese” in Hannover, Germany in honor of Mao’s centennial. But I can find no commemoration of Valentine’s Day in the archives. Not at 1988’s triple bill with the Lazy Cowgirls and Giant Sand in Los Angeles, not in São Paulo in 2001, not on WNYC’s Soundcheck last year. Nothing.
