You must be one of the zillions of Jimmy Buffett fans.    In 2005, he recorded live performances in Hawaii and the Fenwick Park concert that you were wondering about, and they are fantastic. The CD is appropriately titled “LIVE FROM FENWICK PARK”, and has a picture of Jimmy hanging out of the score board sign with the “two thumbs up” signal ,that is supposed to support his work to free the park and the  Boston Red Soxs,  from the well known curse!!  Some people think that Jimmy Buffett and the second Coral Reefers Band, now thirty years since the beginnings, is ever bit as good, maybe better then ever.
