 The tunnel's naming occurred one autumn night in 1975.Several members of The Underground, ALI, FINE, and CRUNCH, had just attended a showing of a new musical-comedy review called National Lampoon Lemmings at the Village Gate downtown.The show (which starred future comic notables John Belushi, Chevy Chase and Christopher Guest) lampooned the Woodstock Festival, which had taken place upstate two years earlier, calling it "Woodchuck" and equating the entire hippie generation with lemmings bent on self-destruction.
