Found this great book at the library - 'The Lost Beatles Photographs'.
Bob Bonis was the US tour manager on the 3 US tours. A keen photographer, he took about 900 photos over the years(some of these included other groups like the Stones).
The main bulk of Beatle pics had never been seen publicly, so his son released them this year. Bob himslef died a few years ago.
Absolutely wonderful, intimate pics of the boys, mainly on stage, some from concerts that had limited media stuff.
