Lawrence Welk: Death of a Square (with special guest Fred Armisen)

Fred Armisen joins Mo to pay tribute to legendary bandleader and TV host, Lawrence Welk. Welk was another victim of television's Rural Purge of the early 1970s, when his long running musical variety show was canceled by ABC after his audience was deemed too old. But Welk did not go quietly. He defied the critics, bringing his show back to life on his own terms - and reaching an even wider audience.
