Thanks Tim & Barbara. Yeah Tim , that's the same tune although a considerably different arrangament. E Carthy's arrangement goes something like:

So what do you think they made of his fins? Sing "????", Sing "????" The finest cases for needles and pins Sing "????", Sing "????" Sing herring, sing fins, sing needles and pins, Sing "????", Sing "????" And indeed I have more of my herring to sing....

...and then on to the next verse....No Chorus! so anyway, its those "????" bits that I can't figure out. btw, it's credited as Trad. arr.E.Carthy,S.Rose,E.Boyd

Thanks again, ....Vic
