The Beatles made their U.S. live concert debut at the Washington Coliseum on February 11, 1964. The band traveled from New York to Washington D.C. by train thanks to a snowstorm hitting the east coast. They performed in front of 8,092 fans. 362 police officers were present to keep the screaming fans from rushing the stage. The noise from the fans was so loud, one of the police officers used two bullets as a pair of earplugs.
The Washington Coliseum was a boxing arena and wasn’t the most ideal venue for a concert. The Beatles had to stop performing and spin Ringo’s drumset around two separate times to allow the rest of the audience to watch the performance. In addition to this, George Harrison’s microphone did not work during the opening song, and he was given a faulty replacement. This didn’t seem to matter to their screaming fans.
It’s possible to find videos of the iconic performance online.
