You can make fun of Paul McCartney all you want, but he’s just going to shrug and whistle all the way to the bank. If you had written a tune this catchy you would say “This is it, lads, this is our golden ticket out of obscurity!” And then you would spend the rest of your life trying to leverage your one moment on inspiration into a steady paycheck. But Paul McCartney can just take one of the catchiest tunes ever written by anyone ever and throw it away as a novelty song about stinky feet. Because he can. That is all.
