An example:

Deep down in 'Old Forest close to Withywindle
way back up in the woods among the water-lilies
There stood a log cabin with the door ajar
where lived a merry fellow named Iarwain Ben-adar
Who never leaved his bounds or explained so well
But he could sing his songs like ringing a bell

Go Go
Go Tommy Go Go Go
Go Tommy Go Go Go
Go Tommy Go Go Go
Go Tommy Go Go Go
Ohh Tom Bombadil
