It’s 1955, and into a square little town in a square little state rides a guitar-playing young man who changes everything and everyone he meets. Loosely based on Shakespeare’s Twelfth Night, this hip-swiveling, lip-curling musical fantasy will have you jumpin’ out of your blue suede shoes with such classics as “Heartbreak Hotel,” “Hound Dog,” “Jailhouse Rock,” and “Don’t Be Cruel.”
