The Rock County Fair may end it's run with an event of historical proportions. Beloit Janesville Symphony Director Michael Krueger tells "Your Talk Show" on WCLO they plan to break the world record for the largest crowd to listen to an orchestra at any county fair. Krueger says the main stage facility couldn't be better, and the orchestra will be using the same sound company as the national country music acts did. He says the music will be very familiar including the themes from Star Wars, Harry Potter, and even Rocky. The Symphony hopes to attract 4000 spectators for the 6:00 p.m. show Sunday night.
