Ne mystery hinny, The boat comes in at North Shields.In Viking days there was a man at the end of the Fish Quay at nights to look out for raiders. One night he's there when He hears a splash of oars so he calls out
"whe's Theor" and from the fog a nordic voice replies "Anna" (The name of the longship ye see!)
wor Canny lad thinks a moment then shouts back
"A Kna ye kna, but I diven't kna cos a cannit see yer thru this fog!"
