In 1964, The Beatles held the top 5 positions on the Billboard Top 100, an unprecedented feat. In this episode of The Music Time Machine, we look back to find how it all happened. From the 1963 UK Tour as just one of the opening acts for the teenage sensation, Helen Shapiro, to the days when Roy Orbison, their own opening act, almost stole their thunder, here is the story of how the Fab Four conquered the UK and the US in two short years. You'll even find out which phenomenally successful group George Harrison inadvertently got signed to their first big record deal.

Here are some of the songs you'll hear in this episode of Beatlemania:

• Please Please Me - The Beatles

• I Saw Her Standing There - The Beatles

• Do You Want to Know a Secret - The Beatles

• Twist and Shout - The Beatles

• With Love From Me to You - The Beatles
