theme song stuck in my head for 40 years

Even though the Spiderman theme song is the most popular theme song from the 60's and still popular today-followed by Captain America, I still know all the words to Iron Man but not the latter two.

Tony Stark, makes you feel,
He's a cool exec, with a heart of steel
And Iron Man, all jets ablaze,
He fights his rights with repulsor rays

Amazing armor of Iron Man
A blazing power...
He's Iron Man

But he wasn't my favorite, Capt. America was. Hulk came in second followed by Iron Man. Sub-Mariner scared me because he looked mean and I didn't like Thor. He was boring and I couldn't understand his Shakespearian style of speech.

I wish there was a DVD box set of Marvel Super Heroes just like the Spider Man set of the 60's.
