== Lyrics ==
:Roll-roll-roll-roll,
:roll-roll-rolling down the hole!
:Heave ho! Splash plump!
:Down they go, down they bump!
:Down the swift dark stream you go
:Back to lands you once did know!
:Leave the halls and caverns deep,
:Leave the northern mountains steep,
:Where the forest wide and dim
:Stoops in shadow grey and grim!
:Float beyond the world of trees
:Out into the whispering breeze,
:Past the rushes, past the reeds,
:Past the marsh’s waving weeds,
:Through the mist that riseth white
:Up from mere and pool at night!
:Follow, follow stars that leap
:Up the heavens cold and steep;
:Turn when dawn comes over land
:Over rapid, Over sand,
:South away! And South away!
:Seek the sunlight and the day,
:Back to pasture, back to mead,
:Where the kine and oxen feed!
:Back to gardens on the hills
:Where the berry swells and fills
:Under sunlight, under day!
:South away! and South away!
:Down the swift dark stream you go
:Back to lands you once did know!
