I spent a few very enjoyable pipe-nerd hours with Harry Bradley on Feb 24th 2012 en route to the Leo Rowsome Commemoration Day in NPU.
Harry tried a few of my chanters and I have uploaded a video of him playing one of my 4-keyed chanters to the Audio & Video page.
The tune I think is “The Hunter’s Purse”- a great version- thanks Harry! It is unknown if the Hunter had matching shoes.
