Believe it or not, The Greatest American Hero theme song was a hit

In Hear This, A.V. Club writers sing the praises of songs they know well—some inspired by a weekly theme and some not, but always songs worth hearing. This week, in honor of our Best Of TV 2013 coverage, our favorite TV theme songs.
As those of us who remember “I’ll Be There For You” by The Rembrandts briefly insinuating itself into commercial radio can attest, a TV theme song seems to cross media and become a hit about once a decade. (BoDeans’ “Closer To Free” was also a hit around the same time, thanks to Party Of Five.) Neither of those did anything for me—that Rembrandts song is almost unbearably cheesy 20 years later—even though my wife likes to tell me that “Closer To Free” sounds like J Church’s “Cigarettes Kill.”
But when I was a kid, I owned a 45 of Joey Scarbury’s “Theme From Greatest American Hero (Believe It Or Not),” and I have a distinct memory of playing it and running around the house while pretending to fly. (The show was a big hit with me and my friends, who were 5 when it premiered.) It’s one of those songs that’s better known than the show it accompanied; I had to look up on Wikipedia what it was even about, because I only vaguely remembered a sort of nerdy guy who becomes a quasi-superhero. (Apparently aliens give a schoolteacher a red suit that gives him super powers, but he loses the instruction manual and has to figure it out on his own. It lasted three seasons!)
