The origin is thus. A poem was written as a tribute to Lord Byron for his speech in the House ( the famous "Their only crime is their crime of Poverty speech" ) when he was trying to get some Poor Relief for the impoverished stockiners of Long Eaton, Loughborough and possibly Fleckney. He was Lord of the Manor of these places and was therefor liable for a major contribution towards their Workhouse costs, so not entirely altruistic. Ironic that the land my Factory stands on, in Fleckney, was built in 1882 to house the largest Sock Factory in the World, and was owned by Lord Byrons descendants.Parsons did put a tune to the words. There is an article on the Ditchling Carol in the E F D S S Journal in 1988 or 89
