Leadfingers,
By the powers invested in me I hereby invest you with Poetic Licence. There you go!

Mr Red,
I completely agree.
But enjamming (enjambment) very rarely occurs in folk song, well, trad folk song anyway. Where it occurs in the original song it soon gets weeded out by the folk process. Unless of course that is the whole point of the song. One of the marvel songs/rhymes uses this device, 'I saw a ......' something about a comet and a peacock's tail.
I know it's also an exercise in punctuation.
