NEW YORK (Billboard) - To celebrate the 20th anniversary of its best-selling album, British pop-metal band Def Leppard will reissue "Hysteria" as a two-CD package October 24.

Beyond a remastered edition of the original album, the new Universal Music edition includes a bonus disc. Contents on the latter include the b-sides "Tear It Down," "Ride Into the Sun," "I Wanna Be Your Hero" and "Ring of Fire," live versions of "Elected," "Love And Affection" and "Billy's Got a Gun" recorded in the Netherlands in July 1987 and extended mixes of five tracks.

"Hysteria" has sold more than 18 million copies worldwide, according to the label, and spawned six top 20 hits on the Billboard Hot 100, including the top 10s "Love Bites," "Pour Some Sugar on Me," "Armageddon It," and "Hysteria."

Def Leppard is on the road with Journey through mid-November in support of its recent covers album, "Yeah!," which debuted at No. 16 on The Billboard 200.
