CHAPIN CENTER SHUTTING DOWN
THE father figure in Bill Thompson's adaptation of ''Hansel and Gretel'' is a performer who lives for art but can't eke out a living. He represents man's spiritual nature, which needs to be nourished against materialistic odds. The theme proved portentous. After last Sunday's twilight performance of the fable at the Harry Chapin Center for the Performing Arts in Huntington Station, the theater, which had been on the brink of bankruptcy, shut its doors permanently. The following evening, the board of directors met and found no alternative but to cancel the balance of the season because of insufficient funds. Regrets to subscribers were mailed yesterday. Tomorrow, the legal steps are expected to begin.
