It's known in Cornwall as "The 3-hand Reel" :

Some say the Devil's dead and buried in Fowey Harbour More say he;s rose again an 'prenticed to a barber

When John's father died, John and I us took a ride Down beside the riverside and home again for supper

It has plenty more "spur of the moment" verses but these seem constant down there. The A music I recall as pretty similar to the Clancy's but for dancing there's a B music too and I've come across a couple of different B's.
