In conversation, Wavy Gravy introduces himself with a self-deprecating giggle as “hippie icon, flower geezer, temple of accumulated error.” It’s a formidable way to sum up the legacy the man born Hugh Romney, whose offbeat peaceful political activism, groundbreaking work with the Hog Farm commune, and unforgettable showing at the Woodstock festival made him a counterculture legend. But, true to his charming humility, this self-proclaimed honorific neglects to mention his monumental charitable work, which has transformed him into something approaching Mother Theresa with a clown nose. A 2009 documentary dubbed him “Saint Misbehavin’,” and that’s as good a title as any.
