BRANDON — A convergence this year of three significant anniversaries, the town of Brandon’s 250th, the Brandon Town Hall’s 150th and WWII’s 70th, inspired Brandon Town Players’ Director Dennis Marden to stage the WWII musical comedy “Kilroy Was Here.” The show, which opened last Friday night and finishes its run on July 15 and 16, is the first major musical to hit the Town Hall stage in almost 30 years.
