After playing dates together throughout the summer and fall. Def Leppard are an English rock outfit hailing from Sheffield, South Yorkshire. Formed in 1977, the band currently consists of frontman Joe Elliott, bassist Rick Savage, and Rick Allen – three of the band’s founding members – alongside guitarists Phil Collen and Vivian Campbell.
