I remember reading an interview with Roy Harper in the "Melody Maker" in the seventies when he said that on some things he was to the left of Trotsky and on others very Right leaning.

The point about his lyrics, was, unlike most of the stuff produced at that time, they made you think.

!And I'm just a social experiment tailored to size,
I've been through the national machine and the welfare surprise
I'm the rich man, the poor man, the peace man the war man, the beast,
The festive consumer who ends up consumed in the feast."

McGoohan's Blues from "Folkjokeopus", 1969

Seven years before punk!
