“Armageddon It” by Def Leppard

"Armageddon It" is the strut at the heart of Def Leppard's Hysteria, the 1987 album that sent it out as a single in 1988, and it gave the band their third US Top 10 hit when it climbed to number 3. Mutt Lange produced, and the writing credit is split six ways between Lange and the whole band: Joe Elliott, Steve Clark, Phil Collen, Rick Savage and Rick Allen.

Elliott himself pegged the vocal approach as T. Rex colliding with Eddie Cochran, plus a stack of harmonies on top, and that's the trick: a glam-rock swagger and a rockabilly hiccup, buffed to a blinding shine, with the Bankrupt Brothers piling on the backing voices. The single came in two flavors, the album's "Atomic mix" and a stretched-out "Nuclear mix".
