Shoreham's Carter Rubin -- winner of season 19 of "The Voice" -- marked an iconic Long Island fun spot's anniversary with a show-stopping performance!

Rubin stopped by Splish Splash in Calverton for its 30th anniversary over the weekend.

The young singing star says it was great to be back on stage.

"I think it's good after this crazy last year that we've had, it's so good to be back and be reconnecting and have live music again. And it feels like everything is going back to normal," he says.
