It is impossible to find truly entertaining entertainment on television. My local PBS station airs one that I tune to. It is the Lawrence Welk Show, which:
...started in 1951 as a local program on KTLA-TV in Los Angeles. The original show was broadcast from the since-demolished Aragon Ballroom at Venice Beach. The show made its national TV debut on July 2, 1955, and was produced at the Hollywood Palladium for 23 of its 27 years on the air. The only seasons not taped there were 1965–66, 1976–77 at the Hollywood Palace and CBS Television City from 1977 to 1979.The show is a variety show of singing, dancing and orchestral music. All the singers have beautiful voices, and the dances are well-choreographed variations on traditional dances like the Polka or the Waltz, or numbers from Broadway show hits.
The show aired on ABC until 1971. When the show was canceled by the head of programming there, Welk formed his own production company and continued airing the show, on independent stations and, often during non-prime time, also on some of the ABC affiliates on which he had previously appeared as well as some stations affiliated with other networks. The syndicated version of the program aired from 1971 to 1982.
Lawrence Welk is the creator, presenter, and conductor of the show. His biography at Wikipedia says that he was born in North Dakota, "in the German-speaking community of Strasburg." He still has a German accent, which he later says was part of his act for the show, although I don't believe that. Despite this accent, he speaks perfect English with all the idioms and colloquialism of a native speaker. Part of his charm is his serious demeanor, which he sometimes breaks with a brief smile.
