It's a setting of a text by William Blake, taken from his work of epistemological liberation America, a Prophecy. The original has some brilliant moments, but for me it's always spoiled by the vocal performance of Phil Minton. With Van that's never a problem, he manages to be plainspoken, gutsy and fuelled by emotion. His call for social revolution is inextricably linked with the spiritual. Still brings a tear to my eye. Just don't go digging too deep in this era of Van's work, this is as good as it gets.
