Neat Touches To Lennon/McCartney songs From George

We all know that McCartney added the frenzied guitar solo to Harrison's
"Taxman."
What, however, are some cool touches on Lennon/McCartney songs that came
from George?
I've read that the major 6 chord that ends "She Loves You" was George's
idea.
And that the changes from 4/4 time to 6/8 time in "We Can Work It Out"
were George's inspired proposal.  (He had done similar time changes in a
few of his own songs.)
What else, anyone?
