See; I knew I connected the dots correctly!
I just Wikipedia'd The Prisoner and realized there are a great many references to it in popculture.
For instance, I distinctly remember either an Iron Maiden song and/or a nineties Hardcore House song (what can I say; my musical tastes have always been... diverse
); it could be either or both, that most likely had a sample from the series: 'I'm not a number, I'm a free man!'
And thanks; now I'm going to have to find a way to watch the series...
