walters approach was different from clarence ashley and sam larner.
09 IN FRONT OF AN AUDIENCE
J C When you're singing at a club or a festival, who do you look at, what do you see when you're singing?

W.P   I don't see anything

J C You don't look at the audience?

W P No, that's why I like a microphone: I'd rather stand up in front of a microphone, than anything, 'cause that's something to look at. That's what I like, this sort of thing in front; you can shut the audience out."
and please dont try and tell me clarence ashleyand larner were not trad singers
