I am glad to have come across this. My only complaint is that this isn't personally one of my favorite songs. I think if it was, I would have given it the full score! This is really quite authentic to the style of the original song. It's nice to know you did this all by yourself. I really do recognize your voice from your videos.
My mom sometimes uses "mister mister", but she says it wasn't from this. I'm surprised, it's a popular song. It makes you appreciate the lyrics more. At 2:36, I love how your voice gets deeper. I can totally see you as the original singer of this. You are talented.
