Happy Days" are here again -- Coming to Palos Verdes Players, Jan. 16-18, are Paul Michael and Marion Ross in the A.R. Gurney two-hander, Love Letters. Ross is best known as the mom on TV's "Happy Days" and had a featured role in film's "Avalon."

Ross and Michael finish a series of four, differently-cast stagings of the epistolary comedy/drama. The show opened Dec. 5 with JoAnne Worley (TV's "Laugh-In," Broadway's The Prince Of Central Park) paired with Roger Perry. The following weekend, Linda Henning teamed with Paul Peterson. Then came Charlotte Rae (TV's "Different Strokes") and Len Lesser. Produced by Susan A. Lyon, Love Letters runs Dec. 5-Jan. 18 at the Players' home on Moreton St. In Torrance, CA.

Gurney's 1989 play traces the lifelong friendship between a young man and woman of wildly different social and political views. Since the play is easy to stage (two lecterns) and can be read from two notebooks, many famous actors have taken turns doing the show in brief runs, as when Love Letters ran Off-Broadway at the Promenade Theatre. Previous players include John Rubinstein, Dana Ivey, Jill Eikenberry & Michael Tucker, Treat Williams, Marsha Mason and Stockard Channing.

Other Gurney plays include Sylvia and The Middle Ages.
