Record Shop folded in the early 1970s; Randy's Record Shop ceased operations in the late 1990s, although as of January 2019, its former building still stands. Allen and Richbourg also had financial interests in recording companies, artist management, and recording studios at varying points in their careers. Each deejay's program lasted from one to two hours per evening Mondays through Saturdays, occupying roughly (with adjustments over the years) the period between 8 p.m. and 2 a.m. Central Time. On Sunday nights, Richbourg or Allen hosted programs featuring black gospel recordings. Richbourg and Allen took credit for helping to start or boost the careers of artists like James Brown, Ray Charles, B. B. King, Otis Redding, Jackie Wilson, Aretha Franklin; Nobles helped the likes of Little Richard. Other than the famous late-night shows, WLAC followed a fairly conventional news/talk (relatively middle-of-the-road politically, unlike today [see below]) and middle of the road music format in the daytime until the early 1970s, when new management attempted to program a Top 40 format, competing against ratings leader WMAK (1300 AM) for the Nashville-area teenage audience. This move, in particular, is believed to have prompted Richbourg and Nobles to retire, as they had no interest in conforming to a predetermined, pop-oriented playlist arranged by an outside consultant. In addition to this, most markets in WLAC's night-time coverage area now had black-oriented stations of their own, most of which attracted the demographic groups that formerly listened to Allen, Richbourg, and Nobles' shows as their only source for R&B and soul music (as it was known by the 1960s). Furthermore, musical tastes among younger listeners in particular changed as the 1970s approached, as white youth began to prefer the hard rock that initially modeled itself on the blues (especially on the upstart FM stations that began playing it), while African-American kids gravitated toward the grittier edges of funk or early disco and, eventually, rap. This made the Motown, Muscle Shoals, and Memphis sounds favored by the DJ trio (Grizzard died in 1971) seem passé, and the hosts' audience, unsurprisingly, began to age, something that advertisers, focusing by then on youth rather ethnicity, almost always react adversely against. Changing tastes also brought about the end to record labels such as Stax, which were major suppliers of music heard on the R&B/Soul shows. To replace the retiring jocks, the station recruited young Spider Harrison, a native New Yorker who
