On the steps of a church hall in suburban Townsville I met a backpacker from New York who claimed they'd booked The Fugs for his high school prom, so we're talking about significant countercultural figures with unexpected links to the mainstream.
Unlike some of his contemporaries (Yippie leader and Chicago Seven defendant Jerry Rubin became a successful businessman) Tuli continued along in more or les the same vein for the next four decade, selling satirical cartoons on the street, performing on and off with The Fugs and other luminaries and, most recently posting his perverbs on a YouTube channel called tulifuli.
What was that line about old dogs and new tricks?
