Hi,
I don't see a narrowboat connection, but here y'go:

JOHN KANAKA-NAKA

I heard, I heard the Old Man say,

John kanaka-naka too-ri-ay.

Today, today's an holiday,

John kanaka-naka too-ri-ay.

Too-ri-ay, O - oh, too-ri-ay,

John kanaka-naka too-ri-ay.

We'll work tomorrer but not today,
We'll work tomorrer but not today,

We're bound away for Friso Bay,
We're bound away at the break of day,

We're bound away around Cape Horn,
We wished to God we'd never been born,
