2 years after Hurricane Katrina, its survivors are still struggling. In about a week, right here in WS, you’ve got two ways to help: The Total Experience Gospel Choir is leading a benefit at Kenyon Hall on 7/8, and advertising right now for more musicians to join in. If you can’t help with that, at least mark your calendar to drop by and chip in — there’ll be good food as well as good music — 1-9 pm a week from Sunday.
