Marvel-ous Earworm: That's Iron Man!

I said yesterday:

(Like the vocalists in the clip, I, too, remember the almost-not-animated 1966 Grantray-Lawrence Iron Man series. Reading up on it today, I learned that it featured both stories and artwork lifted directly from the comics. These cartoons (along with Captain America, Prince Namor, the Incredible Hulk, and the Mighty Thor in the same syndication package airing on CKLW) were my first glimpse of the Marvel characters. They seemed darker but more intriguing than Superman and his friends. I wonder whether the new movie will make such a big deal out of Tony Stark's artificial heart being "transistorized.")

Later, I found the opening theme from the 1966 Iron Man.
