According to the Green Bay Press-Gazette, “‘Jackie Blue’ has a certain structure that happens to sound good on a car radio.” The tune was the first of the Ozark Mountain Daredevils‘ singles to feature drummer Larry Lee on lead vocal. The Montreal Gazette, assuming that the track was sung by a woman, scolded the band for producing a track that sounded like “an outrageous knockoff of Fleetwood Mac’s sound, down to the female lead.” The track hit #3 on the Billboard Hot 100 in May 1975.
The verses are in Eb minor, transitioning to G majvor for the choruses (0:28) and back to Eb for the next verse (0:46), etc.
