The first verse starts off
From Yarmouth Harbour we set sail
The wind was blowing the devil of a gail
All our ring tails set and our baflin is in peak

The chorus goes

With a Big Bow Wow
Tow Row Row Row
Fall der al der I do day

The Ow's are all prononuced like you hurt yourself

If anyone could tell me who wrote it or even where it originated I would be very happy.
