You might try these two sources for info, the Folk Song Society of Greater Boston (http://world.std.com/~fssgb/) or try the Folk Arts Center of N.E., 616-491-6084. Other places to try would be Folk Ats Network which publishes a great calendar every 2 months- call Passims 617-492-7679, they may have a site but I don't know it, also on Thursdays the Boston Globe puts out a calendar that has alot pretaining to folk happenings. Happy hunting
