 The writers originally drew up a list of ten British celebrities they wanted to appear in the episode . The Archbishop of Canterbury Rowan Williams ( a fan of the show ) was included in a draft of the script acting as a tour guide and showing some of his relatives around London . Williams had to reject the part due to other engagements . The script also included a role for a musician ; the staff had hoped to get David Bowie or Morrissey for the part but nothing came together . David and Victoria Beckham were also originally sought to guest star in the episode , and would be seen bickering on the street . The idea was dropped after Blair agreed to guest star , and it was deemed that they were not famous enough in the United States and so were not approached . Jean commented " We thought about it , we didn 't ask . I 've heard of him because my daughter plays soccer . "
