I showed this to the boys yesterday and can't get it out of my head now.  They've also been asking me to sing it repeatedly, a request I've happily obliged.  When I was a kid I loved these Marvel Heroes cartoons (there was also Iron Man, Captain America, and Thor) not just because they were super hero cartoons but because most (if not all) of the episodes came directly from the comic book pages (along with the Kirby art).
