On this day in 1965 The Beatles played to a record 55,000 fans at Shea Stadium in New York. Beatlemania was at it's height and the concert set a new precedence for large scale performance. The volume of the screaming women and girls was so intense that the sound of the fab four was barely audible - the amount of amplification needed to rise above the hysteria wildly underestimated. Even so, it would have been pretty amazing to witness!
