If you are planning to attend the performance of Jean-Eric with Gris Gris Strut at the opening of the Swamp Tours exhibit at the New Orleans Museum of Art (1 Collins Diboll Circle, 658-4100; www.noma.org) tonight, you better get a move on. In Gambits preview of the event (Mime is Money, Music, June 1), we mistakenly said it started at 8 p.m. It actually starts at 6 p.m. and ends at 8 p.m. and is free and open to the public. The Swamp Tours exhibit will be on view until Aug. 29.
