I've come to believe that Henry Lee talks that way as his schtick!! It's absolutely painful trying to listen to him.
I agree. I've noticed that a lot with accents and people who want to manipulate a situation. It has a certain effect on listeners and I think people like Lee use it as a distraction or a way of getting through some things without challenge.
I don't buy it. A hint of accent, yes, but as broken as he speaks.........no way.
I can imagine a great Vegas duet show with Charo and Henry Lee!
