Def Leppard guitarist Phil Collen takes fans on a trip back in time to the beginning of some of their biggest hits from the group’s Hysteria album in a new video interview conducted to commemorate the recent deluxe edition reissue of the LP. It is Def Leppard’s best-selling album to date, selling over 25 million copies worldwide, including 12 million in the US, and spawning seven hit singles. The album charted at #1 on both the Billboard 200 and the UK Albums Chart. Lasting 62 and a half minutes, the album was, at the time, one of the longest albums ever issued on a single vinyl record.
