The songs "sung" by the rising star in this double episode, are actually sung by american singer Chris Isaak (Wicked Game) and can be found among his early hits. The title "Blue Hotel" refers to one of the songs used.
Series regular Josh Brolin and guest star Alice Adair met in the making of this episode and were married. Looking at the rather adult-for-prime-time love scene between them, some of the heat in the scene was real.
