When Who Is 64?

According to the nytimes.com, Yoko Ono is having an exhibition of drawings by John Lennon. The occasion is his turning 64, and it is called "When I'm Sixty-Four." This hilarious for a lot of reasons, but the funniest is how Paul McCartney is always begging her to let him put his name first in the songwriting credits on songs he wrote by himself (Lennon would still get credit, he would just be second), and she refuses. I wonder how many younger people will think that Lennon wrote "When I'm Sixty-Four" now? I'm generally pro-Paul and not necessarily anti-Yoko, but score one for Yoko on this one.
