That's my balliwick, I'm afraid. In addition to the foff List mentioned, foff has a web page and lots more details about Central and all-Florida folk events available at the Friends of Florida Folk WWW site at http://www.foff.org Look for "Continuing Events" & "Calendar" areas.Also I send out a monthly notice with more details on all Central FL folkish events (there are no actual trad. venues) to anyone who sends me their e-mail address, name, city & phone number. About 380 people now.
There's also some Irish dancing club not associated with us if that's what you mean. I can put you in touch. No Irish sessions, per se, but the "tunes" groups are close enough.
I post my list three days before the last Sunday of each month. (12/23 in this case.)
There's also a couple on bars that book "irish" acts that can play loud enough to hear a little of over the talk & drinking.
