Buzag's clarified request was this:

Sorry, should have been more specific. Don't want it for academic purposes - just getting into English music and wanted something not too heavy that might give me a bit more grounding about the important artists, etc.

that being the case, I think that what Buzag needs is Classic English Folksongs, the revision of the Penguin Book of English Folksongs. This link will take you to the index for the book, which has links to MIDIs for all of the tunes in the book. This is a collection of very good songs, a good sample of what have become the "standards" of English folk music. the book is by A.L. Lloyd and Ralph Vaughan Williams, revided by Malcolm douglas (Malcolm posted above). -Joe Offer-
