the Shanty Crew,Make aconcerted effort to be authentic.most other Shanty singers make a fairly good attempt,to make them sound like worksongs. Kate Rusby does not.
neither do I like her interpretation of I courted a sailor,however her diction is good, her arrangements interesting,her breath control good and she has a good voice.
but if commercial pressure forces a singer to sing in a way,that is stylistically irrelevant from the tradition,and not artistically pleasing [Shane Mcgowan springs to mind]and if the majority of u.k./irish revival singers sing in a mid atlantic accent,[and pay no attention to their roots]then it could be argued that the folk revival style is becoming irrelevant to the tradition,in my opinion that is not the case at the moment.
