Strange, Masato -- Book Finder returned no results when I searched for that title and/or author.

Only one of the sites that Google threw up was of any help, saying this:
Roberts, John S. The Legendary Ballads of England and Scotland London: F. Warne, 1887

I guess that's what it is, then. Not, apparently, a well-known ballad collection, I take it.

Thanks all,
Michael
