Wow, I didn't realize I was only 10 when that came out. I felt older than that then! I remember hearing it with a friend when I was probably 14 and my friend commented during the one part (here's where I wish I had a better music vocabulary) that it sounded like people running. She wondered if I thought so too because her sister told her that was dumb. I felt bad for her and couldn't imagine having a sister say that! Anyway, I did know it and like it prior to that but it was only as an adult that I've appreciated what a masterpiece it is, right down to the last, open-ended note. And it was only recently that I heard the line "you gotta give the other fellow hell" properly. I could never figure out what Paul was saying there!
