It very likely that "shine" was involved, but, sounds more like he didn't know how to speak English very well, as was the case for many people of the area in his day. It sounds very much like one of the blues songs we used to play, but, I can't remember the name. A few (very few) of the words that I remember are:
"If you see me coming, better step aside.
Well, If you see me coming, better step aside."
