The song Sgt Pepper's Lonely Hearts Club Band had more overdubs added during this second session, which lasted from 7pm-1.45am.
A reduction mix, titled take 10, was then made to free up space on the tape. Afterwards the instruments were all on track one and all vocals were on track four.
A mono mix, for demo purposes only, was made towards the end of the session. This was subsequently pressed onto acetate discs, mainly to allow George Martin to score the brass parts. These were recorded a little over a month later, on 3 March 1967.
