Who are these players?

I found some old festival photos , but am having trouble identifying some of the players.

Here is the late John Herald and Eric Weisburg on bass, Frank Wakefield's forehead, but who is the banjo player?  This photo is the Greenbriar Boys from 1964.  It should be Bob Yellin, but it doesn't look like him.

This one's from Carlisle in the early seventies.

Uncle Josh Graves on Dobro, but who are the others?
