Doris M Arnett was 29 years old when The Beatles make their first appearance on The Ed Sullivan Show, performing before a "record-busting" audience of 73 million viewers across the USA. The Beatles were an English rock band formed in Liverpool in 1960.

In 1963, their enormous popularity first emerged as "Beatlemania"; as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s.
