The last audio is a shortened version of Cut 17 from the Top News package, from Jam Creative Productions.

Thank you for identifying it!
Also, the station that used that jingle is completely unrelated to WABC! Instead of using library music for their sweeper, they stole music from another station. That's a shame.
I wonder if the other sweepers they made use "borrowed" music from other stations and composers?
