Probably right about Roll, we do Roll more than we Row But if the Liverpool Judies have got us in tow it would be from the shore and they may have been warping ship with Sweeps...large oars deployed as thrusters to move ship around a dock. or a hawser towed to shore by boat so the ship can be warped in by a capstan. both seem to fit so it's singers choice..Yours, (puzzled myself) Aye.
