I ran across this recently, though it was published some time ago. It was written by Stephen Amato and published in 2003. It doesn't look much like Rap to me, but I'm not an expert on that particular form (I am comparing it to the The Script by Fred Lynch). It appears to be more of a rhyming paraphrase. You can preview Amato's work on Google Books.
Who puts a lamp under a bed?
Doesn't he put it on a stand instead?
For there's nothing hid that will not be revealed
All will be known which was once concealed
