A classic theme song from this kind of obscure show from the early 80s, a TV show called Greatest American Hero:
A teacher is asked to be a superhero using a special alien suit with powers he can barely understand or control, after losing the instruction manual. He is aided by a Government Agent. Along with his lawyer girlfriend, they together figure out not only how to control the suit, but to right wrongs. Very great show!!
I dunno for you but I keep hearing (and singing over) George's Answering Machine instead of the actual lyrics :P
