Went to MuseCon, kind of on the spur of the moment. Bonnie and Sam were making a classic 78 rpm record with an old record cutting machine. http://youtu.be/JCHSSXwfhYk Steve was being sound engineer and Bonnie was busily cleaning away the little groove cuttings or "swarf". I'm not sure who was singing and playing, perhaps Bill Higgins knows. Edit: Yes he did!
