In 1964, The Beatles had six number one singles in the USA. I Want to Hold Your Hand , became the number one single of the year on the Billboard Top 100.
Their other 1964 hits include: She Loves You #2, A Hard Days Night #13, please Please Me #16, Twist and Shout #40, Can’t buy me Love #52, Don you want to know a Secret #55, I saw her standing there #95.
The early Beatles were a swing band..... Another great find
