Those jingles still sound outstanding, even though the jingle vocalists lineup changed over the years (some who sang the original KOST jingles are no longer with us). I have Downtown Dayton Radio on my Internet bookmarks and I listen to it occasionally. Before Will Harris chose JAM to update the sound, I think he used the late Ben Freedman Promo Bank series for the acapella “WDDR” sings. I assume he’s still using those when I last checked the station a couple months ago when I first found out that the JAM jingles are in use currently.
Anyway, like I said, those KOST resings are outstanding!!!
