Equestrian Theme New to the Boston Pops

Thinking some plays are better performed inside, the same folks who bring Summerfest to Lexington waited until autumn to stage, somewhat ironically, “August, Osage County.”   Also this weekend, Actors Guild of Lexington performs a police drama dubbed “Breathing Corpses.”  But, perhaps the highpoint this weekend, will be a concert by the Boston Pops celebrating the 75th anniversary of Lexington’s landmark Keeneland Race Course.  Previewing these events is Rich Copley of the Lexington Herald Leader.
