I played the Tom Lehrer track "A Christmas Carol" to a group of Friends last night, and was asked who "Chris Pringle" is (or was). A search on the Internet doesn't reveal a lot - I had assumed he was a North American Santa Claus figure, but I can't find any references, other than to an expert on transport (which would fit in the context) or an evangelic Christian (which wouldn't).

Does anyone know who the Chris Pringle was to whom Lehrer was referring?
