They're not as good as the ones they used, but they certainly are interesting. A company called Adthos has created a visual presentation featuring images - and PAMS-like jingles - as they might have been heard on the old WABC Musicradio 77. I've heard a few mispronunciations of the call letters and sometimes "WABC" isn't quite what the visuals say. (I've heard a lot of W -Ah -BC, which is certainly not how it was said ever on air.)

Neither the station nor the jingle giant was involved in this demo presentation in any way. Certainly an impressive example of what A.I. can do, but I still prefer the originals. 

See and hear them here.
