In 1995, he came out of hiding for the first time in years and did the whole big band thing for the last time
AFAIK for his 50th Birthday Party, with 2 shows, one in NYC and one at the State Theater in Portland, ME. They actually moved in to the State a few days ahead of time and rehearsed intensely. Absolutely one of the best shows I've ever seen the equal of his shows from the seventies. I think the ceiling came down during "Sharon". I saw him again with a bluegrass quintet in an intimate opera house in Camden, Maine several years ago, and that was excellent as well.
