Here is some more "announcer" info.
John Condon lives back east and Warren Moran lives in Arizona.
I probably have a few dates written down on paper someplace that I have not entered.
Alan Berns is still around but I have not been able to track him down.
I have no idea about Bill Martin, if he is still around or any biographical info. He did the Lowell Thomas news broadcasts for many years and filled in once as announcer on "To Tell the Truth", circa 1960.
I am in the process of scanning a lot of old press releases (very slowly on this project).
