found this on another site regarding the recording of p.p.m.
26th November 1962 in 18 takes
(A slower version was recorded 11th September 1962, but erased)
Final mix - mono was one single take, whereas stereo was takes 16/17/18 edited
. . . The Beatles FIRST official L.P. release
For the ONLY time, the mono version was issued 6 weeks BEFORE the stereo version . . .
not sure about the accuracy of this info because it says the slow version was erased and everyone's heard the slow version on anthology

this is alot of attention paid to a small detail. on the other hand - it's one of their best songs, so why not
