This is the principal Mudcat Luddite thread. The lyrics to Duncan MacFarlane's "Rawfolds Mill" are posted there. And the link posted at 21 Nov 05--7:39 AM has oodles of information and song lyrics.

The Yorkshire Garland site has lyrics and audio of "Cropper Lads" and "Foster's Mill".

The reason I know is because I recently completed a series on the Luddites for our local co-op radio station. Podcasts available here -- scroll down to Luddites Part 4 which deals with events in Yorkshire.
