Try the Village Music project, if you can find it. The web site's buried in the Salford University site and has been ruined by being forced to comply with daft web site presentation rules, and Johnny Adams is looking for an independent site to host it. It's also moved to a different address (which I've forgotten) within salford.ac.uk so some Google indexes may be out of date.

The ABC home page has links to collections of music on the web - at least one of these is categorized by country of origin.

The Lewes sessions favourites are also on the web, and many of those are English standards.

Also recommended: Mally's (Dave Mallinson, publisher) "English Choice" series, so far one by Nick Barber and a more recent one by John Kirkpatrick.
