"Say it ain't so," sang headliners Weezer and thousands of concert goers at the 2011 Live at Squamish music festival on Sunday (Aug. 21). It seemed an appropriate way to end the two-day event. Close to 8,000 fans were rocking out and singing along but the time to party at the second annual event was dwindling. Say it ain't so, indeed. The group played a mixture of old favourites and new hits to close the festival and frontman Rivers Cuomo got up close and personal with the fans several times.
