I suppose some people have lower thresholds of embarrassment.

I can honestly say i can't remember the last time I felt embarrassed by a performance. Homicidal...but never really embarrassed. you occasionally meet very odd people in folk clubs.

I suppose if your idea of folk music was the sort of cabaret entertainment that was on offer for much of the 1970's - Walter Pardon might have looked amateurish - but you'd be mistaken he knew what he was doing....you were just in the wrong place, expecting football in a snooker hall.
