Hi, Sciencegeek, are you coming down?
CELTS & CURRACHS is this Saturday, 28 August, in Parade Plaza, New London (just across from the train station; if you head for downtown New London [exit 83 off I-95] and follow the 'transportation center' signs, it is very easy to find; look for the life size whale flukes.
This year:

Brand new young group, talented Celtic Ceol making their festival debut.
Haunting Breton dance music and instruction with Trouz Bras; plan to join in!
Irish step dancing with Spirited Soles, from small fry to world-class competitors.
Irish song with the brilliant Danny Quinn, well known up & down East coast, played for years with the legendary Tommy Makem.
Song, pipes, and more with the amazing MacTalla Mor.

And, it's all FREE.
Street parking is free; there is a public garage too if needed.
