Some years ago I happened upon a session of the Victoria Nautical Song Circle and had a great time. The pub where they met seems to be having licensing issues for music other than by paid musicians, so they might be in a hiatus right now. You can get information here: http://victoria.tc.ca/Culture/Vnsc/

Even if the VNSC isn't currently active the webpage can give you some ideas about what's on and who to contact. I hink the organizer, John Erskine, has a current email.
