Pete Seeger created OLD FATHER HUDSON based upon Seaman's Hymn, which he learned from Lou Killen.

Come all you bold sailors,
Whe-ereever you be;
And tell Old Father Hudson
That we'll set him free!

We have sailed on his waters,
So-o noble and deep;
And the way he's been treated,
[It] would make your heart weep.

May the POWER of the PEOPLE
be-e heard on each shore;
And bring Old Father Hudson
Cle-arwater once more!

The crew of the Danish viking ship Sebbe Als shifted this to Old Father Baltic, substituting Baltic for Hudson.
The capitalizations and hyphenations indicate points of emphasis during the singing.
