Roaring Jelly as the name of a musical group

There are two contra-dance bands called Roaring Jelly:

Roaring Jelly in Massachusetts: is a Boston area contra dance band that has been playing together (in one incarnation or another) since 1970. We play for a monthly dance in Lexington, and appear occasionally at other dances in the area. We also have a facebook page.
Roaring Jelly West in New Mexico: is in the Los Alamos / Santa Fe / Albuquerque area, and plays for contra, square, Scottish, and other related styles of dancing.

Roaring Jelly East: is a new group that seems to be mostly running jam sessions in the Eastport, Maine area.

Years ago, there was a singing group called Roaring Jelly in Australia, but they seem to have disappeared, though some of their recordings may still be around.
