Lizzie: remove the foot from whatever orifice you've inserted it in and go stick EFDSS in the search box on YouTube. Zone in on some of the video from Sam Lee's recent Folk Rising gigs at Cecil Sharp House, for example. That's the EFDSS in recent years, not some received wisdom of a DEAFASS scenario from the 1980s. I know getting facts right isn't your strong point, but . . . since I think you've admitted you've never actually been there, that's the least you can do on your arse in front of a PC screen.
