Start at the mouth then trace the route
Back to headwaters since we doubt
That someone's there but to be fair
We'll check in case we're faced with drought
To find what starts with a whisper and ends in a shout
We tried to swim to get to him
But our arms/legs sunk below
Tied cords of thread around our heads
With which he drew us to his flow
To hear the song that his son sung a long time ago
We found the source, the watercourse
