Here's what's going on today (Thursday, Aug. 9): The musical Avenue Q opens tonight - puppets and all - at Bay Street Theatre. Showtime is 7:30. And it's Open Mic Comedy Night at the Sentient Bean. Tombstalker and Mangled rip it up at the Jinx, the Royal Noise and Those Cats are at Live Wire, Mama's Love plays the Wormhole, and at Yadda Yadda it's Talon, featuring members of the Lovely Locks.
