I remember the tapestry being up for sale. Yes, it was The Atainment by Burne-Jones. I did not realize did not sell and that he still has it. I am glad. To get back to the topic, I have never seen pictures of him at Fen Place Mill, but Alice75 sent me a link of what it looks like and this is the link that you shared, Steve.
The white shelving looks to be Dreanary. I can't think of where else it would be. This is the Tower House music room. It is in William Burges's style, but since none of Jimmy's own belongings can be seen, I am not sure if he keeps his stuff at Tower House.
I was told that he goes back and forth between both residences.
Also thanks for identifying "The Can" bootleg. I wondered what it was.
