The Westhaven Center for the Arts is hosting a to-do called “Let’s Dance,” with the Bayou Swamis providing the tunes for the action. I’ve only ever seen sit-down chamber music performances here, so I am curious to see how expansive the dance floor can get. If you are similarly inclined, you can find out for yourself at 7:30 p.m. for a $5-$20 sliding scale price.
