There is a local radio show here in Detroit on WXRK 97.1 FM that uses a sound-drop during the intro to their afternoon show, something like...
Ding........ ding...... dong do-do-do-diddy-do "The following CBS program is brought to you in color."
So appearently CBS had their own color chimes, not that it makes any sence on the radio.
(WKRK is an Infinity/Viacom station, thus the CBS connection. The talk show is HORRIBLE!!!
Total crap-corporate-fluff that's supposed to be funny, but is little more than an obnoxious 45-y/o bimbo with a smoker's hack, acting like she's 15, over some wanna-be sports-jock who makes fart jokes.... And I'm no prude, I've only heard that intro 'cause the show comes on after Howard Stern (who I enjoy). It's almost fun to listen (In a train-wreck fashion) because the show gets so few callers that they've resorted to having interns call-in and become fake regular guests. Please let this show die as quickly as they previous three that came before it!)
