February 9th 1964, The Beatles made their US live debut on CBS-TV's The Ed Sullivan Show; they performed five songs including their current #1 “I Want To Hold Your Hand”.

Their appearance was watched by an estimated 73 million people. Compare that to the 111 million who watched Super bowl XLV - and not everyone had a televsion in 1964!!   The show had received over 50,000 applications for the 728 seats in the TV studio.  Amazing when you think about it.
