Sunday, Monday Happy Days...Tuesday, Wednesday Happy Days...the whole gang is back! Richie, Fonzie, Ralph, Potsie, and all your favorites from the smash-hit TV series are rockin' and rollin' all week long. The laughs never end in this musical celebration of poodle skirts, jukeboxes, motorcycles and malt shops. 1959 is cool again as the gang gets ready for High School graduation in a sock hoppin', engines revvin' new musical for the entire family. These days are yours and mine.
