In the video for "Down This Road", by the Wrights, when it reaches about the minute mark, I swear that Alan Jackson walks into the background and plays guitar for about twenty six seconds. It is a little out of focus, but I think it's him. I don't know if you are supposed to notice it, but sure enough he's there in plain sight. He isn't given any special credit or anything. Correct me if I am wrong. I just thought it was cool for some reason.
