This gem off of the white album is a strong contender for the most complex song ever performed by the fab four. As stated in my previous post, this song was an inspiration for the Let It Be-project due to the fact that it required everyone to be on the top of their game and not simply session men for the songwriter.
Lennon's composition is almost schizophrenic in it's constant change of style and time signature. But it all sounds very natural; an effect of this being a very tight group who had played together about ten years at this point in time (a couple of them far longer). Everyone pulls together and the result is really amazing. McCartney is on fire and John delivers one of his most compelling vocals of the whole album. Give it a few good listens whilst reading along with the music to get a feel for the song before attempting to play along.
A few clarifications may be in order; 12/8 is of course shuffle, so 9/8 is basically 3/4 in shuffle time. I orginally wanted the 5/4 measures in letter F to be 10/8 but Finale doesn't recognize this as a valid time signature. Just listen and read along and you'll get it.
