I don't think "Music 'Till Dawn" was a network show, but a "franchise" (much like TV's "Romper Room"), done at each individual station.
Exactly. Not even really a "franchise," just a show title that was commonly used by CBS stations. I don't know about any others, but both KNX and KCBS had live local DJs on
Music Til Dawn.
An analogy is the Westinghouse TV stations that generally called their local news programming in most markets
"Eyewitness News." In that case, a number of ABC stations picked up the title in markets that didn't have Westinghouse owned stations. So for example, KABC-TV in LA had (has)
Eyewitness News, but KGO-TV San Francisco did not, because Westinghouse owned KPIX was already using the title. Obviously, Westinghouse never copyrighted the brand.
The same was probably true of
Music Til Dawn which likely found it's way to non-CBS stations.
