Def Leppard Is Back!!!

After selling over 65 million records, Def Leppard decided the time was right to pay tribute to their musical heroes on their new cover album Yeah!. The boys from Sheffield, England, are staying busy these days: They were recently saluted by VH1’s Rock Honors and on June 23 they’ll kick off a U.S. tour with fellow ’80s stalwarts Journey. PEOPLE caught up with frontman Joe Elliott, 46, about the band’s cringeworthy moments and what really happens behind the scenes at a Def Leppard concert.
