As The Beatles’ last album came out and there was outrage from fans all over that the most dynamic group in the world was coming to an end, The Beatles were still as dynamic and innovative as ever, even on their way out.
Not only did they go out with a bang (Abbey Road is an amazing record), but they also never officially had an end. The last song on the record, “Her Majesty” ends abruptly, so it sounds like there was no end.
This kind of says something about life in general, you never really know when things end — they just do. You just have to accept it for how it is and appreciate the experience for what it was.
