plane. At first a flight attendant is trying to force her to sit down. The message cuts off and Ross frantically tries fixing the answering machine, wondering out loud if she got off the plane. From behind him, Rachel appears and says she did, and they get back together for good. The following morning, the friends gather in Monica and Chandler's empty apartment and reminisce about how all of them had lived there at one point or another. With some time remaining before Monica and Chandler leave for their new house, the six all leave their keys to the apartment on the kitchen counter and decide to go for one last cup of coffee together, to which Chandler sarcastically and jokingly quips, "Where?" and they all laugh as they head down the hallway. The final shot shows the empty apartment, slowly panning around from the living space to the front door as Jefferson Airplane's "Embryonic Journey" plays. Production Writing and music The series' creators completed the first draft of the hour-long finale in January 2004, four months prior to its airing on May 6. Before writing the episode, David Crane, Marta Kauffman and Kevin S. Bright decided to watch the series finales of other sitcoms, paying attention to what worked and what did not. Kauffman found that they liked the ones which stayed true to the series, and they found the finale of The Mary Tyler Moore Show to be the gold standard. The writers had difficulty writing the finale, and spent several days thinking about the final scene without being able to write a word. Crane said that they did not want to do "something high concept, or take the show out of the show". The music playing as the camera pans across the empty apartment at the end of the episode is "Embryonic Journey" by Jefferson Airplane. The song "Yellow Ledbetter" by the band Pearl Jam is also featured in the episode—after Rachel boards the plane for the first time—making it the first Pearl Jam song to be licensed for a television show. A spokesperson for the group said it was, "simply a matter of the show's producers asking permission". Filming The episode was filmed in Los Angeles, California on Stage 24 at Warner Bros. Studios, where Friends had been filmed since its second season. The first part was taped on January 16, and the second on January
