Thanks to Sean over at the Kenwood blog for sending me this awesome photo! The post right below this one shows John and Yoko sitting at a table holding hand. I stated that I wasn't sure if a fan took it, but I could imagine someone above the couple calling out their name and snapping a photo when they looked up.
Well....as you can see in this photograph. It does sort of look like a fan who took the photo (see the part that is circled?). So cool!!
