“Theme from The Greatest American Hero (Believe It or Not)” by Joey Scarbury
In a decade filled with great television theme songs, the theme from The Greatest American was among the best. In the late ’70s Joey Scarbury began working for producer and composer Mike Post. Post was hired along with Stephen Geyer to write the theme tune for a new TV series titled The Greatest American Hero.
After recording the full-length version of the song, entitled “Believe It or Not”, it was edited down to a minute for broadcast as the theme song for the show. The show became successful, and everybody loved the song. So the song was released as a single, and peaked at #2 on August 15, 1981. Scarbury could not follow up the song’s success. He did team up with Mike Post again to record “Back to Back”, which was the theme song for Hardcastle and McCormick.
