Trivia: Walter Koenig's recurring Psi Corps character, Bester, was named in honor of science fiction writer Alfred Bester, who coined the term "psi cop" in one of his many novels about psychic manipulation.
Trivia: J. Michael Staczynski wanted to create mature, adult science fiction not a kids' show. His rule was that any cute kids that appeared in an episode had to be killed off by the end of that episode (e.g. "Believers" and "Confessions and Lamentations.").
Trivia: Straczynski planned out Babylon 5's entire story arc from the beginning. He kept a written copy of it on a 200-page encrypted computer file. Straczynski never revealed his full plans to his writing team until the very end of the series. He intentionally included red herrings in the plot so that viewers would not be able to predict the outcome of the series.
Chosen answer: It was a piece composed expressly for the episode by Christopher Franke, who simply called it "Bar Background Music."
