Paul McCartney is 73, and can certainly boast a long and successful career in music. McCartney rose to fame as one of The Beatles, and he will always be known for his work in the legendary band. However, he has still chosen to tour and share some of his newer music, so it looks like Paul McCartney won’t be slowing down any time soon. He even collaborated with Rihanna and Kanye West for the hit “FourFiveSeconds.” Paul McCartney, whose net worth is $730 million, was also recently honored with The Art of McCartney, a tribute album composed of 42 songs.
