Studio Two (control room), EMI Studios, Abbey Road
Producer: George Martin
Engineer: Ken Scott
With the White Album nearing completion this was a session devoted to the creation of mono and stereo mixes.
It took place in the control room of Abbey Road's Studio Two, from 7pm-5.45am. A stereo mix of Everybody's Got Something To Hide Except Me And My Monkey was the first to be tackled, followed by five of Helter Skelter, two of Mother Nature's Son, and four of Ob-La-Di, Ob-La-Da.
Mono mixes followed. Again, Everybody's Got Something To Hide Except Me And My Monkey was the first, and was completed in a single attempt. It was followed by two of Mother Nature's Son, one of Ob-La-Di, Ob-La-Da, and one of Long, Long, Long.
A satisfactory mono mix of Helter Skelter had been made on 17 September 1968, meaning no other was required on this date.
