Hmmm...I read somewhere about the Children's Crusade, but memory (faulty at best) seems to recall the involvement of a hermit calling them to march on the Holy Land. I'll have to look it up when I get my library back from the bookcase building frenzy out there.
Don't recall any ballads about it, unless there's something contemporary in one of the history books pertaining...If anything shows up, I'll let you know (setting tracer), but it would be a few weeks. I don't know where much of anything is out there, except the stain and the polyurethane.
