Sorry for resurrecting an old topic, but I figured I'd post this here. A couple weeks ago, I was looking at The Beach Boys' Web site, and saw they had an interesting tour date:
2/10/18 - Orlando, FL - Universal Studios Music Plaza Stage
Just checked this morning, and the date has been removed from their site. I'm not sure if they're no longer appearing at Mardi Gras, or if they were not supposed to announce anything yet. But, there's a strong possibility The Beach Boys are the first act to be unofficially announced for the event.
