Paul? "Paul"?

At Getty Images' blogsite, I found an article about photographer Duffy who did a photo shoot of Paul or "Paul" for the Sunday London Times when the musical track for the film The Family Way was being scored.  Take a look at the November 1, 1966 photos at:  http://blog.gettyimages.com/2009/12/28/duffy-captures-paul-mccartney .  I took a close look at the two photos. (There are additional photos at the getty images website with the subject search "paul mccartney 1966".)  I don't think it's Paul.
