"It was originally a poem and if I ever read it as such I promise I'll punctuate it as such. Until then, while I choose to sing it, I'll arrange it and perform it any way I want. Of the many times I have done so, no one has ever complained that I got the punctuation wrong in that line."

That's because almost no one knows or cares what this poem/song means, and they are quite content to enjoy it as a meaningless but tuneful jumble of words and images, or to impose on it whatever fanciful interpretation comes into their heads. See the pertinent threads for examples of same.
