Cover art for Medicine Show lyrics by Big Audio Dynamite

Scratch that last comment (not that anyone else has read this lyric in the past two years). It's most likely about the widespread drug use of the 80's, specifically cocaine, and how it had a controlling affect on both the rich and powerful as well as the lower class. The Clint Eastwood sound samples make one think of crackpot medicine salesmen in the old west.
