WAV, you haven't answered the points I've raised about the song. Child's introduction to it (implying it's probably Scottish), the fact that you don't know where the tune you sing was collected, the fact that you don't know where the words you sing were collected.

You could be singing a Scottish tune to American lyrics for a song which is probably Scottish in origin, though no one knows for sure. How does this correspond to your narrow definition of English music?

See what we've been saying? You can't put cultural and geographical parameters around this music. Furthermore, if your "scholarship" consists of googling whatever version of a song you can find, even YOU - who preach to people about what music they should be singing, and how - can't vouch for the provenance of the material that you've absorbed into your repertoire!

I think if you're going to operate at this level of dogma, WAV, you need to be a bit more academically rigourous abut your sources.
