Some songs are just enjoyable because they sound good without making that much sense.
I am not usually a fan of those type of songs, but I concede there are some songs that hit the mark for me for that very reason. This is one of those songs. I’m sure someone knows what on earth Paul McCartney is singing about. I’m sure his fans know what he’s on about. I’ve heard this song tons of times and I don’t have the foggiest.
Still a cool song though. Enjoy.
