So what are we to make of Blake's "Jerusalem"?

It's something Bob Dylan would have written, had he been around in 1808, when the only public assistance available was workhouses and debtor's prisons, the workday in those "dark Satanic Mills" was a full twelve hours, and children toiled in the pits at collieries and were treated worse than draft animals.

Parry's setting of it does it musical justice.

But that's just my opinion.

What do you make of it?

to tolerate listening to it more than once.

Yank anglophile. It is a very weird anthem, dark satanic mills and so on.

England (as opposed to Britain) has it memorized. It's basically the English Anthem.
