The photo below was probably shot by Lizzie Bravo.
13 March 1967
Studio Two 7.00pm-2.30am

Recording "Good Morning, Good Morning" (SI onto take 10)
This was the brass overdub which featured on the released mixes.

These photos appear to be Paul leaving the session.
I would make a wild guess the acetate Paul is holding is an undocumented mix of this night's
work or possibly "Getting Better" which had been the focus of the most previous sessions.
