The picture, drawn back in 1967, depicts the four of the Beatles as they might look in 40 years from then.... That was the year of the release of the wonderful album Sgt Peppers Lonely Hearts Club Band, feuaturing the song When I'm 64 .
Today two of them are no longer with us and the other two do not look much like that picture - thy look much better. The reason might be the music they create.
Happy birthday to Sir Paul!
