Backmasking
"Fire On High" contains a backwards message in the beginning. When the song is played backwards, the message voiced by drummer Bev Bevan can be heard stating, "The music is reversible, but time is not. Turn back. Turn back. Turn back. Turn back." — ostensibly Jeff Lynne's shot at backmasking hysteria, after false satanic allegations were made against their song "Eldorado" by Fundamentalist Christianity members. "Down Home Town" also starts with some backmasking: the refrain from "Waterfall" ("Face the mighty waterfall, face the mighty waterfall"). A portion of the string crescendo from "Nightrider" was used backwards on "Evil Woman."
