The Day Def Leppard Made History

Back in 1983, Def Leppard had hit the big-time. The band's third album, Pyromania, turned into a multi-platinum smash, largely due to the success of singles "Photograph," "Rock of Ages" and "Foolin'" (all Top 40 hits in the U.S.). Although the album didn't go over huge in their native Britain, Def Leppard were genuine superstars in America.

About a year after the release, the Leps entered the studio to capitalize on their success with a follow-up record, sure to be another hit. But it wouldn't be that easy.
