There are few entertainment bargains as good as The Freeman Stage in Fenwick Island. On June 15, join the Mid-Atlantic Symphony Orchestra and the U.S. Air Force Academy’s Blue Steel Band for “An American Celebration.” Julien Benichou leads the orchestra in a program of light classics. Blue Steel, comprised of active-duty servicemen, performs music in several genres. You’ll hear jazz, patriotic pops and, yes, some rock. Bring your lawn chair. (436-3555, freemanstage.org)
