Through the hills and hollows, three Billy goats are rollin’ to a gig at Nanny May’s Shimmy Shack, home of the best barbecue and boogie music around. But to get there the billies have to cross a bridge . . .and deal with a mean old troll. As each billy zooms up, the troll threatens to smash his instrument to smithereens. But that old square gets a heaping surprise when the rockin’ billies take him to Nanny’s, where he tastes her famous barbecue and hears that rockabilly beat. Before long, the troll hits the dance floor to rock and roll at every Rockabilly gig from that night on!
