Chris Ridley's site lists in Cornwall (I link to it) and when I was in Falmouth there was a session on the Tues in Jacobs Ladder (at the top of the steps called....) Wed was an open stage/mic night. I waqs told by Pete Grassby not so long ago that the Gunnards Head hotel near Zennor still have a bash on Wed night.
