Former Beatle Paul McCartney turns 70 on Monday, and as the distinguished musician enters another chapter in his life, he shows no signs of slowing down.

Paul McCartney gained worldwide fame by making his mark on the music industry as one-quarter of The Beatles.

Along with band mate John Lennon, he took the Fab Four to the top of the charts and became one of the most celebrated songwriters of the 20th century.

With his career extending way past the 10 years that The Beatles remained active, Paul McCartney has racked up 60 gold discs, sales of over 100 million albums and singles, and is said to be the most successful songwriter in UK chart history.

While his Beatles song Yesterday has been covered by over 2,200 artists -- more than any other song in the history of recorded music -- McCartney formed Wings with his first wife Linda in 1971, and used his ingenious ear for melody to write songs like Mull of Kintyre, which is one of the best-selling singles ever in the UK.

McCartney has written or co-written 32 songs that have reached No. 1 on the Billboard Hot 100, and as of 2012, he has sold over 15.5 million RIAA-certified units in the United States.

In June, McCartney closed the Queen's Diamond Jubilee Concert held outside Buckingham Palace, performing a set that included classics like Let It Be and Live and Let Die. It has also been confirmed that McCartney would receive the honor of closing out the opening ceremony of the 2012 Summer Olympic Games in London in July.

With all the he has accomplished and will continue to accomplish, McCartney says that he has no intentions of hanging up his hat any time soon.

If I'm really enjoying this, why retire? he told Mojo last year. People say to me, 'You work so hard', added McCartney. We don't work hard, we play music.

To this day, Paul McCartney remains one of the world's top draws. Playing to more than 100,000 people, his two performances in Mexico City in May 2012 grossed nearly $6 million.
