Can’t answer why but where: Styx’ third album “The Serpent Is Rising” rereleased by RCA as “Serpent” after they went to A&M and made it big. It’s an unlisted track near the end of Side 1.
Krakatoa is a poem which leads into their rendition of the Hallelujah Chorus and concludes Side 2.
Dennis DeYoung blasted this album in an online chat. Mentioned some songs but not Plexiglass Toilet. As he explained it, Styx II’s lack of success compared to their debut made him not trust his instincts. So he tried out some goofy stuff.
Seems he returned to form on “Man Of Miracles” and when Lady broke in 1975 he was confident again. Maybe too confident!
