Bob Blake[not a source singer,but still a good singer is listed] in folkepedia,but no Harry Cox [an excellent source singer]
BobRoberts accompanied himself,as did John Mcdonald[TheSingingMolecatcher],neither of these two are listed in folkopedia as source singers.,but most people think they are source simgers.
Pecker Dunn[is he a source singer or revival]banjo.
RichardBridge,Wheatstone made concertinas not F.....Accordions.
Fiddles were used on board sailing ships,but generally for hornpipe competitions,not shanties,which as far as I know were generally sung unaccompanied,please correct me if I am wrong.
Margaret Barry[afine singer],isnt mentioned in folkopedia,I am not sure,but most people assume,as I have done in the past that she was a source singer.
