Def Leppard are a British heavy metal band formed in 1977. They are still active to this day. The band had mild success over the course of their first two records, touring with AC/DC and singing to a major label, but they didn't make it big. That was until the release of their third album, 1983's Pyromania. It was their first record with guitarist Phil Collen who joined the band after they kicked out original guitarist Pete Willis for drinking too much. The album went to #2 on the Billboard charts, kept from the top spot by Michael Jackson's Thriller. This original Def Leppard two-sided raglan, worn in and lightly discolored, is from Def Leppard's tour in support of their 1983 album Pyromania.
