If you want to have a good old-fashioned time and help out a worthy cause, gather up the kiddies and head out to today s St. Peter Home Picnic on the St. Peter Village grounds, complete with a petting zoo, games for kids, a car sweepstakes, a spaghetti dinner, and, if there is a supreme being, Pronto Pups. Tonight s Memphis Jam Concert Series at Mud Island Amphitheatre (with a $3 admission!) is by the Violent Femmes, Porch Ghouls, Marc Broussard, and Stout. Di Anne Price is at the Blue Monkey Midtown tonight (if you haven t eaten at the new Downtown Blue Monkey, by all means do so). Brad Postlethwaite, Circuits Made Simple, and 3 Pipe Problem are at the Hi-Tone. And Foreigner is at Sam s Town.
