Hi Bradfordian,
You may be interested to check out this link:
http://www.ceili.unh.edu/
It is for a local (seacoast New Hampshire) radio show on college radio, which specializes in music of the British Isles. At that link site, you will find a calendar that will certainly help you. Roland Goodbody (the DJ) has posted dances, concerts, sessions, workshops and events, one month at a time, all in the English, Irish and Northeast American traditions.
I notice that he only has March up right now, but he usually does keep two months up at a time. Keep checking back, and you'll surely find something that interests you... if you happen to be in the southern New Hampshire/southern Maine area, that is.
Have a great visit!
