Check out this quote. There've got to be photos somewhere:
"Nudity is no stranger to the theater of Terrence McNally, who once told a reporter, "I like to zap an audience." From Sally Kirkland' s bondage strip in "Sweet Eros" to John Slattery's bathroom sojourn in "The Lisbon Traviata," states of undress have been just one of many strategems in the McNally zap. A device once employed as a cold-shower shock, however, becomes in "Love! Valour! Compassion!" a warm, lake-water illumination: By the time the eight men bare their bodies, what we see is caring and human frailty."
