From the unusual teamups department: Back in 1976, Jack Kirby --the X-Men, Fantastic Four and Hulk co-creator -- got the chance to go backstage at a Wings concert and meet Paul and Linda McCartney, where he presented them them a picture he'd drawn of them with the X-Men villain Magneto (left). Even better, there's a photo set of the two legends coming face to face.

There's also an excerpt from an interview with Kirby's daughter Lisa here, where she says that Paul "introduced dad in the audience, and then he went into the song 'Magneto & Titanium Man.'"
