 This episode was due to be transmitted on 27 December 1988 but was  postponed at the last minute and replaced with another episode  because Pan Am flight 103 had exploded over Lockerbie in Scotland  six days earlier on 21 December 1988, and the episode features two  Christian spirituals "Talking on the Phone to Jesus" and "Gonna Go  to Heaven on a 747", written by Dean Friedman.
