Some nice Beatles references in Jonathan Lethem's "My Marvel Years," about Jack Kirby (and Lethem-as-comics-reader), over at the London Review of Books:
Nevertheless, if you (I mean, I) accept my premise that the mid-to-late 1960s Fantastic Four were the exemplary specimens, the Revolver and Rubber Soul and White Album of comics, and if you further grant that pulling against the tide of all of Kirby’s inhuman galactacism, that whole army of aliens and gods, was one single character, our squeaky little Sue, then I wonder: Invisible Girl, the most important superhero of the Silver Age of comics?
...who spend our time casting wonderful spells, and sending Beatle-y emails to each other. After several centuries of this one of us put down his computer and said, "Why not turn it into a blog already?" And that, kiddies, is how the zebra got his spots.
