Paul once said about his instrunment playing, I tend to think about his vocal talents, he's not and incredibly good singer (i.e. a la Orbison whom you'd pay to hear him sign out the telephone book, acapella) but he's very versatile.
Just as good belting out an "I'm down" or "Oh Darling" as he is on softer songs like the intro of "Carry that weight", or falsetto "Girlfriend"... still waiting for him to a rap song (LOL).
People are crazy, times are strange
I'm locked in tight, I'm... out of range
I used to care, but... things have changed
