Dolly Parton wrote this song to be the theme for the 1980 film 9 to 5. The film, which was Parton’s acting debut also starred Jane Fonda and Lily Tomlin. The film was about the plight of secretaries in in the American Office.
At different points in the song, you can hear the sounds of some metallic tapping followed by a bell.
For those old enough to remember it, this was the sound of a typewriter, which was the tool of the trade for secretaries in 1980.
