The Lawrence Welk Show is an American televised musical variety show hosted by big band leader Lawrence Welk. The series aired locally in Los Angeles for four years (1951–55), then nationally for another 27 1/2 years via the ABC network (1955–71) and first-run syndication (1971–82).
In the years since first-run syndication ended, The Lawrence Welk Show has continued to reach new audiences through repeat episodes, broadcast in the United States by Public Broadcasting Service (PBS) stations. These airings incorporate an original program—usually, a color broadcast from 1966 through 1982—in its entirety. In place of the commercials, newer performance and interview clips from the original stars and/or a family member of the performers (in the latter instance, speaking for a well-known Lawrence Welk performer who has since died) are included; these clips are occasionally updated.
