Back in the early 1970s, Jack Kirby was invited backstage to meet Paul and Linda McCartney at a Wings concert in LA. For the occasion, Jack drew a really nice illo (below) of Paul and Linda with Magneto, and we did a write-up of the event (courtesy of Gary Sherman) in The Jack Kirby Collector #43.
Now, through some amazing detective work, Rand Hoppe (curator of the online Jack Kirby Museum) has managed to track down an audio clip of McCartney introducing Jack to the LA crowd during the show. You can hear it, and see Jack’s drawing much larger, at the Kirby Museum site (and if you haven’t joined the Museum, get to it!):
