In recent days, I’ve done more scribbling about Paul McCartney than I ever imagined I would do. You remember that he used his celebration at the White House — he had received an award — to tell the crowd how stupid George W. Bush was. The Obama audience loved it, cheering, laughing, and applauding. Now he’s back with an interview in the Sun — spotted by my colleague Bob Costa, the Baronian wunderkind. As you know, some years back, global-warming campaigners hit on the idea of calling their opponents — global-warming skeptics (many of them top-flight scientists) — “deniers.” That was meant to be parallel with Holocaust deniers. Al Gore is only one of many who use this term “denier.” (I once asked Václav Klaus about this. And he said, in essence, “Well, then, I’m denier-in-chief.”) Okay, here’s McCartney, saying that the oil spill in the Gulf could have a positive effect, because it would wake people up to the badness of oil: “Sadly we need disasters like this to show people. Some people don’t believe in climate warming — like those who don’t believe there was a Holocaust.” Another issue, real quick. The other day, I pointed out the interesting fact that Vice President Biden referred to President Obama, in public, as “Barack.” The Beatle does the same: “I don’t accept the criticism of Barack over the oil spill. I think he’s been great.” And just one more little lick, from the McCartney interview: “When it was the election I was praying he would win and dreading John McCain or Sarah Palin getting in. It was like, ‘No, America — you don’t need that right now.’”

Well, I’m like, I don’t need any more McCartney right now — so I’ll stop for a while! (“Penny Lane” is a pretty tune, regardless.)
