The single “All You Need Is Love”/”Baby You’re a Rich Man” was released on July 7, 1967, and reached the #1 position in every major country that had a pop chart. After the live broadcast, the Beatles took much of the rest of the summer off to plan for their next project. “All You Need Is Love” was written specifically for a worldwide television broadcast called Our World, which was the first ever live global television broadcast on June 25, 1967, and was watched by 400 million people worldwide.
