Joe, All the dates I know of are at the link posted by Steve:

Not sure why they aren't on Arn's site. I'll check with the booker on that. Jesse lives about an hour north of NYC. There's a regular circuit of clubs, dances, and festivals around the Northeast that keeps his band busy. Their website: www.jesselege.com/
In case any of you might make it to London (UK): Jesse will be playing with Joel Savoy in The Cajun Barn in London (www.cajunbarn.co.uk) on March 18th!
