Where are they now? Vol. 2

I did one of these a LONG while back, and thought it might be time for some new questions...

Bob Caldwell - He sang with The Kingdom Heirs, Brian Free, Won By One, and was the "original" bass singer for the "New" Statesmen that Gaither gathered. A really great bass singer!
Where is he now?

Ed Crawford - Ed is best known for his time with The Kingsmen, but also spent time with The Singing Americans. The last I had heard of him he was with the Mystery Men Quartet. He may still be, but if so, then the question becomes where are they?

Scott Whitener - Another former Singing American. Scott spent some time with a few other groups, but I have no idea where he is now... Do you?

Help me (us) out here, OK?
