Johnny always sounded kinda nervous and wired to me.
In this set, he references taking some shots of cocaine, but that wouldn’t make someone sound like this.
Plus, you don’t take shots of cocaine, you snort lines.
Well, not you specifically, though it’s possible you may, but that business is between you and whatever gods are present in your drug addled state.
Anyway, sounds to me like he was more on methamphetamine than anything.
Explains the shaky voice and the sweats, plus the fact that he was in Fulsom prison.
