Here is a website with many photos of the Revolution. You may find him in the crowds. I've seen a few individuals who look like him there. I have the other photos you're talking about, but whereas some think those are him, I have doubts.

Here is one from 1979 that I think may be him. He's a little guy and his clothes drape on him the same way they do in this photo.
