In the heady days of 1965, I gave George Harrison a 12-string guitar as mentioned here. I forgot about this other photo taken by Bill Carlson until I learned it was part of a book by him about that same Beatles concert in Minneapolis. Thanks to Dominic Cleary for digging up these docs, I didn't even know they existed. The photo is available as a large format poster no less!

The book is called "The Beatles: One Night Stand in the Heartland"
