Anjelica Huston, escorted by Jack Nicholson, was among a small group of family and friends who took part in a private funeral service Monday at Hollywood Memorial Park for the late director John Huston. The memorial service took place in the Abbey of the Psalms mausoleum, according to a family spokesman, and Huston was interred in a mausoleum beside the remains of his mother, journalist Rhea Gore. The time and place of the service had been kept secret until it began. Huston's son Danny greeted mourners who arrived by limousine outside the small chapel. A public memorial service is expected to be held in about two weeks, the family spokesman said.
