This is something interesting from the Beatles Anomalies List:
Edit, and the rhythm guitar drops out in mid strum. This is between "cry" and "instead". It is suggested by Stephen Moss that his dual-voiced part on "cry" is not tight at all, especially compared to previous examples in the track. It almost sounds like he's about to run into difficulty singing at all. (Reference the "I'm crying" bridge in the Anthology version of I Am The Walrus... Does he just have issues with the word 'cry'?) At the cut, on "instead" suddenly the vocal snaps back into line.
George is having problems with the lead guitar. Note how low he is mixed, compared with the first bridge at 0:45. Critical listening shows that he's fumbling some of the runs, and is only mixed back in clearly when the playing improves.
