Now try to picture Richie, Potsie, Ralph Malph, and the Fonz belting out showtunes. Unfortunately, the stars of Happy Days A New Musical arent the original Arnolds Malt Shop gang, but this bubbly road show does at least boast the imprint of Garry Marshall, creator of the 70s sitcom. Still, ya gotta wonder whats next. Petticoat Junction? B.J. and the Bear? God forbid, Joanie Loves Chachi? Garry, say you wont.
