So, there was this one time in 1976 when ex-Beatle and then current Winger Paul McCartney met Jack Kirby, the King of Comics.
I’d read about this before once…on Wings’ follow-up to their smash hit Band On The Run album, (entitled Venus And Mars), McCartney featured a song called “Magneto And Titanium Man”. Both characters are Marvel Comics villains, and one (Magneto) was co-created by Kirby. This led to Kirby being invited to a Wings concert that was held in L.A. in 1976.
Kirby, his wife and his daughter went backstage and met McCartney and the rest of Wings, and Kirby gifted Paul and his wife Linda this picture:
So yeah, Kirby and McCartney.
