It was all big: the barn dance in Dave Rowell’s big yellow barn in East Craftsbury, VT, last night; the crowd (hundreds); Dave himself (at the mike with the Starline Rythmn Boys); the fried chicken sandwiches served up by the Craftsbury General Store; the rebound in the barn’s wooden floor when the band played Whole Lotta Shakin’ Going On. The biggest Northeast Kingdom social event of the spring. To benefit the Craftsbury Public Library and the Craftsbury Chamber Players. Only in Vermont does a rockabilly band play to nurture the appreciation of chamber music.
