You can find an absolutely wrenching version of "Close The Coalhouse Door" on "The Wilson Family Album" I recently bought a "NEW" copy on vinyl. It's on Harbourtown Records, Number HAR 020 released in 1991.
The Wilsons are a Family group from the North East of England and they do almost all their stuf A Capella. Real Meaty harmonies and mega powerful voices. I caught them at the Gainsborough Folk Festival in October 2005. "Sooz" may have contact details for them.
