I have been looking at this photo and I do not believe it is Duane. It seems that most people accept it as Duane but I say otherwise. I have several issues with this photo but the one that, I think, points to this not being Duane is the haircut. In this pic, it looks like this guy has a sort of layer cut to his hair. You can see the front of the haircut. But Duane did not have such a haircut. Duane's hair was just long. He either pulled it back behind his ears or he let it hang down in front of his eyes. The hair on this guy does not look like Duane's hair. Here is the pic. I would welcome any thoughts on this.
I have seen this pic discussed many times for years, the prevailing wisdom being that it is not Duane. Unfortunately, like many mislabeled things on the internet, it just will not go away.
