Circa November 1966 - April 1967
I have found no way to definitively date these photos. My source simply dates them as during the "Sgt. Pepper" sessions.
The ones of Paul with the moustache are definently during "Pepper". I suppose there is a possibility those of John, George and Ringo could possibly squeek into the Magical Mystery Tour
sessions. The photos are of The Beatles arriving or leaving E.M.I. Studios. The last three of Paul and last one of John are at Paul's home. The photo of John and Paul in the hall was shot by Lizzie Bravo
. This last photo of George in the booth is probably 19 January 1967 but I cannot verify that.
