Where Did All The Pauls Go?

When you start researching Paul McCartney's disappearance in 1966, you assume there was Paul and then there was his one replacement who shows up in November, 1966.  It's a little unnerving at first as you delve into the mystery and find that there were several other Pauls who were photographed at various times from 1963-1966.

One was a Paul who appeared on the Beatles' 1966 tour,  (see photo on right.)

And you start wondering, what happened to these "other Pauls"? 
I was looking for photos of Paul in 1966 and I found a photo of what looks like the "Paul" on the right.
