You can buy a wonderful cd called "Guide Cats For The Blind" - the proceeds of which go to a charity for blind people to have access to computers (a cause dear to my heart) - on the cd are various performances by Les Barker, and Cyril Tawney himself doing parodies of his songs including Sammy's Bar...it's available from Amazon.

I particularly like Martin Carthy's "Hard Cheese Of Old England" and June Tabor's "Git Along Little Dogie"
