Ruth mentioned three compilations a little earlier. Walter features on them all; the EFDSS cd, due for reissue later this month, A Century of Song ('Bright Golden Store'), the Voice of the People sampler ('The Poacher's Fate'), and Hidden English ('Broomfield Hill').

These are excellent compilations, covering a wide range of traditional singers from Britain and Ireland; a very good introduction if you are interested in learning more. They can be bought via the links above (the EFDSS online shop doesn't have details yet, though); samples of the Topic cds can be heard at various places; the first that came up were:

Hidden English (CD Universe)

Voice of the People (CD Universe)
