This reminds me of GMA Radio Television Arts theme too

12:07 From the news specialists in Southern Colorado, this is Eyewitness News Tonight with Sandra Mann, Harv Holliday and J. Ralph Carter. (KOAA-TV/K30AA Pueblo-Colorado Springs)

So this is the package where the jingle of GMA 7 in the Philippines came from.

I think WMGC in Binghamton, NY used this after they switched their callsign (Which they would do again in 1998), but don't quote me on that

7:30, 9:30 - 10:29 - This was used for WTVN-TV Channel 6 (currently now WSYX ABC 6) in Columbus, Ohio back around the late 1970s.

6:19 somehow reminds me of the opening theme from the 1970s game show, “To Say the Least”.
