No ,I think the point was that women didnt sing in pubs very muchin EastAnGlia[The BlaxhallShip,TheEElsFOOT],and rural areas,That doesnt mean they didnt contribute to the tradition.MargaretBarry was a street singer/busker,later she played in folk clubs in England[another traditional performer given a platform by the revival],she may well have played/sang in Irish pubs in london,but LONDON in the 1930 1940 1950,was more all embracing/less conservative than rural east Anglia,at that time.
