Pedant Alert !!

Sea Shanties were Unaccompanied Work Songs , so a fiddle playing a shanty would NOT suit the Folk Police at all !

However as Shanties were NOT approved of on Royal Navy vessels , a fiddler would often be utilised to keep the men pulling together .

Any suitably rhythmic tune would serve this function , but if you have a shanty singer who is NOT a purist and wants a fiddle accomp . Go For It !
