Here's one we used to sing at Scout camp. Near as I can remember it went like this:
(chorus) Barges, I would like to go with you
I would like to sail the ocean blue
Barges, have you treasure in your hold?
Do you fight with pirates brave and bold?
Out of my window looking through the night
I can see the barge's flickering light
Silent flows the river to the sea
And the barges too go silently.
(chorus)
Out of my window looking through the night
I can see the barge's flickering light
Starboard shining green and port is red
You can see them flickering far ahead.
(chorus)
One of these days, I know it won't be long
You will look for me and I’ll be gone
Facing to the wind, far out upon the sea
Where the whales and dolphins sing to me
(chorus)
