A search for "jack of all trades" "folk songs of britain" (the parentheses are vital!) returned 161 hits, of which Google displayed 20. They were almost all "lyric" sites or discographies, but there were three results from dealers. One is a year-old list, another is one of those damn-fool time-wasters that lists stuff he doesn't have (in this case a cd; which of course doesn't exist at all) and Rockinworld. I've never bought from them, but I know the name, and they often have things like this. It's just practice, really; learning the best ways to ask the questions.
