FOX ended the series with this episode. The final episode was never aired in the US. It did, in fact, air in a few countries in Europe later on.
Nikki DeLoach performed the song "Love Sombody" that M.J. was suppose to be singing. Nikki DeLoach also sings the song for M.J. in the episode 21(the series finale).
The series ended on this episode despite having a full episode order of 21 because the ratings with a strong lead in were not where FOX wanted them in their prime time lineup.
