Great illustrator, great poet, great republican. The song Jerusalem actually comes from a longer piece called "Milton" which has a prose preamble raging against the then war against France. Seen in that light, the poem is a protest poem, not a patriotic hymn. That it was set to music to rally the English during the Geat War is irony personified. Blake would have been horrified. After saying that, Parry's song moves me everytime I hear it. The sentiments remain true and do not lie.
