You know about "Jersey Boys," the wildly successful jukebox musical that tells the real story of Frankie Valli and the Four Seasons. It's an engaging tale of 1960s pop stardom, conflict and small-time mobsters. The Broadway musical that arrived at the Marcus Center Tuesday night could be called "Memphis Boys." It's about the only time three legends and a pioneering rockabilly artist jammed together at Sun Records Studio, the Memphis storefront recording business that birthed 60 years of pop culture.
