I was listening to a wonderful site of vintage radio broadcasts yesterday. It's called Reel Radio and it's located at http://www.reelradio.com/
One the main page, if you scroll down to the new additions for November 24th 2002, (Reel Radio hitbound) Their is an aircheck you can listen to for Tiger Bob Raleigh, WPGC Washington D.C. 1969. At about 1 hour and 33 minutes into the aircheck, you can hear Roger Davis doing voice over for a Polaroid commercial!
Check it out, it's a great blast from the past!
