What happens when you're one half of the biggest band in the world, and then when that band ends, you form another huge band and go on to sell millions more records, including a 'James Bond' theme tune? And then, when all that's said and done, you continue to write and release records for another fifty years? You become a billionaire, and one of the most successful and beloved performers in all of music history.
Whether it was in the Beatles, or Wings, or just on his own, Sir Paul McCartney has entertained all of us for many years. He's written some of the best-known songs of all time, and it's impossible to imagine what popular music would even look like today had he and John Lennon never met. McCartney is a committed vegetarian and a supporters of animal rights causes. He even once wrote to the Dalai Lama to tell him off after he saw him eating meat!
