Eddie Murphy, whose popular street-wise persona was satirized by Robert Townsend in his film "Hollywood Shuffle," will join Townsend as a special guest on Fox Broadcasting's "The Late Show" tonight. While on Murphy's boat (the two are pals), Townsend--who is the current guest host in the procession that followed Joan Rivers' dismissal--invited him on the show at the suggestion of "The Late Show's" producer, John Scura. The all-female group Klymaxx will also appear. The program will air on KTTV Channel 11 at 11 p.m.
