Pack up your picnic dinner, put on your toe-tappingest boots and come join JP and the OK Rhythm Boys for their free Concert in the Park on Sunday, July 21, 5-7 p.m. in the Village Green. JP, Gordon and Anita will keep you humming, singing, sighing and laughing with their inimitable mix of fiddle, guitar, bass, and three-part vocal harmonies with a side helping of mandolin, ukulele, banjo and of course a seasoning of musical saw. New songs and old, new jokes and old, from swing to hoedown to cowboy tunes to jazz standards, to waltzes to originals, to … well, you never know what will catch their fancy, and yours.
