Jim Carroll, I am telling you that Fred Jordan developed his technique,singing in a pub or at home to a few friends is completely different,from singing to a hundred people on stage at a folk festival.
Your opinion on stagecraft,does not interest me.,any more than your opinions on concertina playing,or anything else you know nothing about.

Fred Jordan was afine singer,and an excellent performer who could adapt to many environments, pub singarounds, folk clubs, folk festivals.
Performance like Music is a learning process,a good performer learns from mistakes and develops and improves,
