Break out your pearl-snap shirt and your best dancing boots for Vergennes Opry — er, Opera House’s season-opening event, Honky Tonk Vaudeville. For one night, two of Vermont’s premier country-western bands keep the dance floor full with toe-tapping tunes of love, loss, juke joints and drunk tanks. The Hokum Bros. pick and strum lively Americana strains, sneaking some satire and social commentary into songs such as “Tastes Like Chicken” and “Made in China.” Folks get to hootin’ and hollerin’ when the popular Starline Rhythm Boys (pictured) bang out their raucous brand of rockabilly, with plenty of twang. Libations by Bar Antidote keep spirits high at this good ol’ fashioned hootenanny.
