The Beatles were arguably the biggest pop band of the 20th century. During their time in the spotlight, they came out with a number of very popular and enduring hits, including "Hey Jude", "Don't Let Me Down", "Yellow Submarine", "Helter Skelter, "A Day in the Life", "Here Comes the Sun", "Twist and Shout", "Strawberry Fields Forever", "Lucy in the Sky with Diamonds", and of course the incredibly popular and catchy "I Want to Hold Your Hand". Written by John Lennon and Paul McCartney, in October of 1963, "I Want To Hold Your Hand" was recorded using four-track equipment and more than one million copies were ordered in the United Kingdom alone prior to its release, highlighting the sheer obsession fans had with the Beatles, which was sometimes dubbed "Beatlemania". The four-piece band publicly announced their split in December of 1970, crushing hearts around the world, after John Lennon privately told his bandmates that he would be leaving the group in 1969. Though the band did not continue on for as long as the world would have liked them to, their passionate fans keep their music alive today through remembering the lyrics to and still singing along to songs like "I Want to Hold Your Hand". Though John Lennon and George Harrison have both passed away, they are survived by former bandmates Paul McCartney and Ringo Starr who no doubt find comfort in the fact that their loyal fans still remember the lyrics to their famous songs, all these years later.
