eheh, listening to "Love Thy Will Be Done" on the Prince Originals comp made me think of this thread... only to find out I had already written the EXACT same thing I was planning to post !

Regarding "Tomorrow Never Knows" I think I remember McCartney actually saying in the Anthology or something that Lennon was just strumming the C chord throughout the song and how unusual and new it was for them.
