While winter is plodding along, many may be looking ahead in yearning for summer. The State Theatre offered up a bit more enticement on Tuesday. The Downtown Easton venue announced that The Beach Boys have joined the venue’s summer calendar, circling a June 27 show. Mike Love, the lone original Beach Boys member who still tours using the band’s name, has long been continuing to bring the music of one of the most iconic American bands in history to the masses. His group is embarking on its “Endless Summer Gold” tour that is set to kick off Feb. 21.
