June 25, 1967: The Beatles perform ‘All You Need Is Love’ on Our World, the world’s first live television satellite link-up to be seen by approximately 400 million people across five continents. The satellite link-up was devised by the BBC. Personalities, including Maria Callas and Pablo Picasso, from 19 nations performed in separate items from their respective countries. The event, which lasted two-and-a-half hours, had the largest television audience to date.
“Brian was very excited about the idea of the broadcast which led to ‘All You Need Is Love’. He came to me and said, ‘Look, there’s an international hook-up with all nations and the Beatles have been chosen to represent it. We’d be doing a live broadcast to 200, 300 million people in every part of the globe.’ In those days that was unbelievable, because television was very limited. So he was enormously excited about it, and very proud of the fact that the Beatles were leading the way. It was very good that it was a very successful broadcast.
Of course, Brian was using it as an opportunity. He was offered the broadcast and he took it, but he could see that the Beatles were going to become important artists without necessarily having to tour.”
