Today marks a very special occasion in the music world. 73 million American viewers tuned in to watch a little band from Liverpool, England perform on “The Ed Sullivan Show” 50 years ago.

Exactly 50 years ago today on Feb. 9, 1964, The Beatles first introduced themselves and developed what we now claim as “Beatlemania.”

Step back in time with this historic video from “The Ed Sullivan Show.”

Opening with “All My Loving” the “youngsters from Liverpool” had girls in tears. Screams accompanied the song as Paul McCartney joyfully sang, bobbing his head.

Black and white shots of the audience captured the true impact The Beatles had on American culture at that time.

“Till There Was You” and “She Loves You,” was followed by “I Saw Her Standing There” and “I Want To Hold Your Hand” later in the show.

Even Elvis Presley joined in welcoming the Beatles to America on “The Ed Sullivan Show” that very first night. During the program, Sullivan announced that Presley and his manager, Colonel Tom Parker, had just sent the band a telegram wishing them success in the U.S.

I so want to go to the Ed Sullivan Theater today- they changed the marquee to make it look like it did 50 years ago when The Beatles played.
