Thank you, Sir Paul
I think yesterday's Super Bowl Halftime performance by Sir Paul McCartney provided at least one valuable service - millions of tivo owners will now know, thanks to his crystal-clear enunciation, that all the lyric sheets in the world (not to mention, if memory serves, Penn & Teller) are wrong, and that the line is actually, "But if this ever changing world in which we're livin'..."
Makes sense, always has, but everybody wanted to just be all smart and intelligent and point fingers at Sir Paul.
Moral: Don't point fingers at Sir Paul.
