Need help finding the name of an old song.....

Here's the words.....
So bend ya backs and row me Lads, tomorrow night we sail
We sail into the harbour, no prouder men we'll be.......
We'll show them all we've captured the monster from the sea....
Maybe a Schotish or Ire-ish band...?
Someone may know...?
Dog_ger needs some help again...
Thanks dudes....
70's or early 80's...?
Maybe an oldie will pick it up...?
