I answered a while back ...
Liverpool -- Mendips, Penny Lane, Strawberry Fields, Jacaranda, Matthew St., etc.
London -- Abbey Road, Marylebone Station,
NYC -- The Dakota gate, Strawberry Fields, Shea Stadium.
At Shea, I was working as a photographer and got to go down on the field. I walked in from a gate in centerfield (I know, wrong way), and the crowd was roaring at the event, and I for just beyond second base where the stage was set up, and gave a quick wave over my head like they did getting into the getaway car. Of course, no one was paying any attention to me, but it was fun. :-)
But an update -- did Hamburg this year. Stood in the doorway of the photo John used for "Rock and Roll." Saw the Reeperbahn, the outside of the clubs, the theater of burned-condom fame, etc. It was OK. Yes, BeatlePlatz, for the person who asked. Nothing really special about it.
