You can probably get the cd via retailers such as http://www.musikfolk.co.uk/, who have it listed. What sort of quality you will get is another matter; Dave Bulmer and Celtic Music of Harrogate have a bad reputation, and, if the experiences of a number of people whose records have been reissued by that label (typically on CDR and without their knowledge) is anything to go by, no royalty would go to Billy Pigg's heirs from any sale. Second hand copies of the vinyl can be had; http://www.rockinworld.com/ has one listed at present at $15.00.
