I first heard Jerusalem performed by ELP, and despite their somewhat overwrought, I don't know, kitchyness?, I think they captured some of the passion of Blake, one of my all time favorite poets.
I think my favorite lines,
the part where the rabbit bites its own head off, are
Bring me my bow of burning gold!
Bring me my arrows of desire!
Bring me my spear! O clouds, unfold!
Bring me my chariot of fire!
