Broadcast on the first live television link, “All You Need is Love” was written by Lennon and McCartney after they were asked to write a song that everyone could understand. This being the height of the counter-culture movement of the late 1960s, “All You Need is Love” encompasses the best qualities of the Beatles: their sincerity, their talent, and their humor. As wonderful as the message is, what really makes the song is the burlesque trombone after the chorus is sung each time. And if you make it all the way to the end, Paul starts singing a little “She Loves You” for good measure. The broadcast was watched by 400 million people in 68 countries, so hopefully somebody got the message.
