To mark the awe-inspiring 93rd birthday of folk legend Pete Seeger, a group of local performers come together to present "For Pete's Sake" -- an all-star, in-the-round, anything-goes Pete Seeger celebration! They'll tell stories and, in the true Seeger tradition, lead lots of singalongs. This year's performance features troubadour Chris Buhalis, the family trio Gemini (featuring San and Laz Slomovits with San's daughter, Emily), Erin Zindle (of The Ragbirds) the "Music to Cure What Ails You" duo Mustard's Retreat, Lansing singer and song community builder Sally Potter, Angelo's chronicler Dick Siegel, and singer-songwriter (and Fourth Ave. Birkenstocks owner) Paul Tinkerhess. All proceeds from tonight's show benefit The Ark!
