Fred Jordan learnt The Benefit Concert from Albert Shaw. I wrote about the connections between the two men in the extensive biographical notes that accompanied Fred's double CD A Shropshire Lad on Veteran (2003). Fred said Albert knew "some awful rude songs". Some of the information came from Eric Shaw, Albert's son, who went to folk clubs in the 1960s and beyond - I met him at Sidmouth festival.
Elaine - is Eric your father or uncle?
