From what I read, McCartney wrote this melody when he was 15. At that age I was still figuring out how to play „Silent Night“ by heart. What a f… genius. John gets no credits here. He called this wonderful tune „Paul’s granny shit“.
C / sped up to C# on the recording
Nothing special to mention. Bass strings should be muted, but not too hard.
April 2016: Added intro and second bridge, some corrections, new layout .
