The Beatles songs became increasingly sophisticated, both in theme and musical complexity. Sgt. Pepper’s Lonely Hearts Club Band released on June 2, 1967, was considered a high-water mark of artistic achievement. Just a few weeks after, on June 25, 1967, the Beatles recorded “All You Need is Love,” live on the “Our World” program, which was the first ‘global’ television broadcast. It was viewed by over 400 million people in 25 countries. The song captured the spirit of the “Summer of Love.”
