(LEARNIN') Harry Smith is best known for the mind-bogglingly extensive and annotated compilation Anthology of American Folk Music (close to my heart because it contains the best song ever recorded: "I Wish I Was a Mole in the Ground"). Apparently, he also grew up in Bellingham, made direct-animation movies, and collected paper airplanes. Who knew? Soak up Harry Smith arcana at the lecture "Revisiting the Anthology of American Folk Music" at 5:30 p.m. (Northwest Film Forum, 1515 12th Ave, 800-838-3006. $3 for the lecture, $30 for a full series pass.)
