Classic shows — largely, from 1967 to 1982 — were repackaged with new footage (either Welk or the show's cast introducing segments) for syndication during the 1982–1983 season as Memories with Lawrence Welk, after which they were withdrawn from distribution for a short time.
In 1985, The Lawrence Welk Christmas Reunion was produced.
Reruns continue to air to this day (in many markets airing on Saturday nights at 7 pm, the same time the show aired during the latter years of its original run), with new and updated interviews with surviving cast members (Mary Lou Metzger hosts wraparounds that feature interviews, while Bobby Burgess currently hosts the ones that do not).
The shows are occasionally "recut" and interspersed with segments from other episodes for time and diversity purposes; for example, a rebroadcast of Gail Farrell's 1969 debut actually featured an added song by Anacani, who hadn't joined the show until 1973.
The first was that the network had to cut three-and-a-half hours a week of prime-time programming, owing to the institution of the Prime Time Access Rule in 1971; the other was the fact that Welk's viewership was mostly of people over forty-five, mostly because of the music he chose to play, but also because younger viewers, the core viewing target that networks coveted, were either out during the Saturday night slot, or were watching one of the other networks.
Over the course of the early 1970s, several variety shows (including Welk's, but ranging from long-running series such as The Ed Sullivan Show, The Hollywood Palace and The Red Skelton Show to more contemporary shows such as Hee Haw, The Johnny Cash Show and This Is Tom Jones) were pulled from network schedules (particularly ABC and CBS) in a demographic move known colloquially as the "rural purge".
Welk's program was among a group of syndicated niche programs, others including Hee Haw and Soul Train, that flourished during this era.
Due to the fact that stereophonic television had not yet been invented (it would be 25 more years before it would become standard), ABC instead simulcast the show on its radio network, with the TV side airing one audio channel and the radio side airing the other; viewers would tune in both the TV and the radio to achieve the stereophonic effect.The primary sponsor of The Lawrence Welk Show was Dodge (automobile maker), later to be followed by Geritol (a multivitamin), Sominex (sleep aid), Aqua Velva (aftershave), Serutan (laxative), Universal Appliances (manufacturer of home appliances), Polident (a denture cleanser), Ocean Spray (fruit juice) and Sinclair Oil (automobile fuel) served as associate sponsors for a short time.(During later years, a number of Welk cast members appeared in commercials for many of the show's sponsors, filmed specifically to air during Welk broadcasts.) While the show was highly rated and continued to attract more audiences, ABC canceled it in 1971 for two reasons.The 1965-66 season was taped at the Hollywood Palace because that was ABC's only West Coast TV studio at the time equipped for live or taped color production; Welk had insisted that the show go color in 1965 because he believed that being broadcast in color was critical to the continued success of his program.Once a couple of studios at the ABC Prospect and Talmadge facilities had been converted to color in 1966, the show moved back there. When the show was cancelled by the head of programming there, Welk formed his own production company and continued airing the show, on local stations and, often from 7 to 8 P. Eastern Time on Saturdays over some of the ABC affiliates on which he had previously appeared, along with some stations affiliated with other networks.
