Paul McCartney has sex on his mind at 76. Maybe that’s why he looks so youthful. His new single is called “Fuh You.” Yikes. A little different kind of stuff from the man who wrote “Eleanor Rigby.” Maybe he’s been listening to a lot of Kanye. Anyway. it’s damn catchy, because that’s McCartney! This is the third track he’s released in advance of “Egypt Station” coming September 7th.
