Does Harker have anything to say about John Leyden? He was around at the same time as Scott and Motherwell, impressed the heck out of everyone who knew him, but left only a small paper trail. I put a couple of anonymous songs on my website which I think must have been his work (who else could possibly have reworked Hafiz into a topical Scottish song?). What he published under his own name tended to be overblown (like that vast ballad about the demoniac aristo who ended up getting boiled in lead) but maybe he could do better when he wasn't trying so hard?
