The distinctly psychedelic look and sound of the fabulous 60s returned to Tamaqua on Thursday evening at the train station when the LargeFlowerheads, a 1960s Lehigh Valley-based revival group, serenaded a sizable gathering during the weekly Tamaqua Chamber FreeSummer Concert Series. The familiar, foot-stomping tunes had the crowd singing and swaying. The concert wassponsored by Lehigh Anthracite LLC.
