I don't listen to John Scott, so for a half-second I pictured John Collins (traffic reporter) in my mind. I have a friend who does a killer John Collins. Almost as good as my Scott Walker impersonation. But seriously, folks...
I've heard the Reel Radio airchecks of WAPE and KHJ and have thought, "Why can't anyone have fun anymore? This stuff is awesome!" I have also read John Long's book at oidar.com about back in the day. Oh well.
Ditto to everyone's suggestions, especially of walking music encyclopedia Steve Fox. I would also add Tom Murphy and Rick Baron to the list, as well as one of the last great overall talents--who unfortunately is out of radio--John Harrell.
Finally, for what it's worth, let me predict now that Chase Daniels will be around for a long time. I can't stand top 40 music, but anytime I hear WAPE in a store or restaurant, or flip past it in my car, Chase always seems to be having a great time hosting his own weekday afternoon party.
