With Mike Post handling the music for both tracks on this single, the A-side is a Joey Scarbury piece only due to his vocals.  Despite sounding a bit like elevator music in parts, and having significant cheesiness to the singing and guitar, the “Greatest American Hero” theme is a powerful earworm, thanks to its hooky chorus and melody.  The “Hill Street Blues” theme is much more sedate in comparison, though it brings in the same chintzy electric guitar, but it shows a greater level of nuance to Post’s song-writing.  A neat little piece of ‘80s pop culture ephemera.
