This new fundraising special, THE WELK STARS - THROUGH THE YEARS, will salute 18 hard-working, much loved Welk entertainers, using vintage photos from the network television years and clips from the past PBS Welk Specials. The show will be hosted by Mary Lou Metzger who will share an upbeat detailed short biography of each performer, illustrated with carefully chosen material, ending with each featured Welk Star in a major production number.
