Relive the summer of love when the Happy Together Tour 2019 makes a stop at The Palace Theatre. Some of the biggest names from the ’60s and ’70s — The Turtles, Chuck Negron (formerly of Three Dog Night), Gary Puckett and the Union Gap, The Buckinghams, The Classics IV, and The Cowsills — will transport fans back to the sunshine and psychedelic-tinged sounds of the past. Sing along to “One,” “Over You,” and more, without breaking out the vinyl.
