It's been half a century since the Beatles began their first recording session. Since then, they've made their way into the upper echelon of musicians and became an icon for today's greatest bands.

To honor 50 years of hard work, below is the band's famous live performance in the U.S. on the Ed Sullivan Show in 1964. The February 9 performance is estimated to have drawn in about 73 million viewers.

Their music still rings true, as one of their most well-known songs, "Come Together" was covered by their compatriots, the Arctic Monkeys, during the opening of this summer's Olympic Games.
