Believe It or Not (Theme from "Greatest American Hero")

A lot of pop culture history to cover here, so bear with us. "Believe It or Not" was the theme to the 1980s TV series The Greatest American Hero, and by far the biggest hit for the adult contemporary singer Joey Scarbury, who also charted with the follow-up single "When She Dances" (#49), and back in 1971 with "Mixed Up Guy" (#73, written by Jimmy Webb). Scarbury has also had some scattered songwriting success, including "No Matter How High," a #1 Country charter for The Oak Ridge Boys.

This song was written by Mike Post and Stephen Geyer, a songwriting team who are also the names behind "Back To Back," the equally catchy theme for the '80s TV series Hardcastle & McCormick. They've also worked a lot with mighty TV mogul Stephen J. Cannell. Post also wrote "Theme From Hill Street Blues" and "Theme from The Rockford Files."

This is the answer most people guess for the question, "What TV theme song was a #1 hit in the '80s?" The correct answer: The Miami Vice Theme by Jan Hammer. "Believe It or Not" spent two weeks at #2, but never hit the top, held off by the Diana Ross and Lionel Richie duet "Endless Love."
