Just saw this thread. All the info above is good. As Joe's "Mr Nowell Sing We Clear" (I think), not from Connecticut, but currently from upstate New York via Vermont and originally Worcestershire and Anglesey, I will say that we (NSWC) learned it from one of the Sheffield Carol publications, probably from Ian Russell.

Doing our Xmas program based from Vermont, Nowell Sing We Clear changed the line "Yet Britain must the stranger know" to "Yet we must all must the stranger know" since our touring schedule mostly takes us through NEW England.

We kept the "Britannia" reference though :-)

We have been touring and recording since 1975. The show changes some every year. We will be on the road again starting in the first weekend in December. This year we have a performance at the Millennium Stage in Washington DC, so there will probably be a video archive on their website.

Should anyone be interested, our recordings (including Jacob's Well) may be sampled at the site Joe mentioned above (Golden Hind Music).

And Joe, no-one in England would think that I have a pronounced British accent. I'll be testing this out next spring when I go back for a short tour with Debra Cowan. I'll see what it's like taking Coals to Newcastle.
