(SONGWRITING SPECTACULAR) The inspired goofballs of Seattle School bring their mind-blowing, crowd-pleasing, Genius Award–winning, real-time songwriting competition and obstacle course back to the Crocodile, for a battle royale between Billy Joe of the Dusty 45's and Lori Campion of the Hot Rollers. If you've never experienced the chaotic magic of Iron Composer, don't miss it. If you're already a convert, go again—because tonight there'll be curious TV bigwigs in the house who deserve to witness a complete blowout. (Crocodile, 2200 Second Ave, 441-5611. 10 pm, $10, 21+.)
