The Lost Beatles (continued)

In the last post, I described the Bob Bonis photograph collection book I read.  Again, I don't think Paul or John came to America on the last Beatles tour of 1966. 
In my December 7, 2010 post, I told you about the website that has photographs from the book.  It's at:  http://www.nfagallery.com .  (And, again, this isn't an advertisement for the site or book.)
They've changed some of the photographs, but if you take a look at the Paul McCartney labeled photos [click on photographs on the left of the site and then click on Paul McCartney], you can see in photos #6 and 15 from Cincinnati; #17 from Philadelphia; and #25 from Detroit (all from the 1966 tour, although the Detroit photos are mislabeled at first as 1965), the subtle differences in the facial features of "Paul."  It wasn't  Paul.
