Wednesday Happenings

Self-Promotions

-- The nation of Canada rolls its promotion wagon into Copley Square this week, and it's a 47-foot-long streetcar. If you have forgotten that Canada exists, the Canadians are here to remind you, with mounties, oysters (in a month without an "r"!), and a chance to win a trip to the Canadian city of your dreams. Copley Square, 8:00am-8:00pm. Free.

-- Wanna see a pair of brass balls in action? Author James Frey, who was chewed out by none other than Oprah for fabricating parts of his "memoir" A Million Little Pieces, is back promoting his novel Bright Shiny Morning. America is a land of second chances. Presented by Brookline Booksmith. Coolidge Corner Theater, 290 Harvard St., Brookline, 6:00 pm. $5. (CR)
