It was 46 years ago today that the Beatles' took over the music charts and, as far as I know, it's an achievement that has NEVER happened again.

The Beatles had made their first U.S. appearance barely two months before and "Beatlemania" was sweeping the nation.

Today in 1964, the Fab Four held the top 5 spots on the Billboard Hot 100 Chart. "Can't Buy Me Love" was number one, followed by "Twist and Shout," "She Loves You," "I Want To Hold Your Hand," and "Please, Please Me."

What you may not know is that they also held down the top SIX spots on the Australian charts-the same week.

On this anniversary, I thought I would give you a "Number One This Week/Behind The Music" extra to start off your week.

According to Steve Turner's book, "A Hard Days Write:"

It was January 1964 and the Beatles were in Paris for 18 days of concerts at the Olympia Theater. To keep the songwriting going, they had a grand piano moved into their hotel suite. This is where Paul came up with the song. It was Producer Ge0rge Martin's idea to start the song with the "chorus." Although "She Loves You," and "All My Lovin'' were used in the film "A Hard Day's Night," "Can't Buy Me Love"  was the only previously-released song to be included on the soundtrack. This was because it was pulled into the film at a late stage to replace "I'll Cry Instead," which director Dick Lester didn't think was right for the scene in question.

American journalists asked Paul in 1966 whether the song was about prostitution, he replied that all the songs are open to interpretation, but that suggestion was going too far.

Happy Anniversary to Paul, George, John & Ringo on this musical milestone.
