At several points in this episode, Felix Staples (
John Cameron Mitchell) breaks out into a song, "Prepare Ye the Way of the Lord." Despite the quasi-apocalyptic context and Staples's professed religiosity, this song is not a hymn; rather it is one of the first songs from the 1970s musical
Godspell (1973), composed by
Stephen Schwartz, with a book by J
John-Michael Tebelak. Like many of this show's regular and guest actors, Mitchell is an acclaimed Broadway musical performer, having appeared in such shows as Big River, The Secret Garden, and, most notably,
Hedwig and the Angry Inch (2001) (which he also co-created with
Stephen Trask).
