A Sea Song

Oh, for a soft and gentle wind!

I heard a fair one cry;
But give to me the snoring breeze

And white waves heaving high.
And white waves heaving high, my boys!

The good ship tight and free;
The world of waters is our home,

And merry men are we.
There's tempest in yon horned moon,

And lightning in yon cloud;
And hark the music, mariners !

The wind is piping loud;
The wind is piping loud, my boys,

The lightning flashing free
While the hollow oak our palace is
Our heritage the sea.
