"Work It Out" is a 1996 song by British hard rock band Def Leppard from their gold album Slang. It was released as a single later that year, reaching number six on the US Mainstream Rock chart and number 22 on the UK Singles Chart. The song was one of two songs, the other being Slang to be featured from its parent album Slang on their greatest hits compilation albums Best of Def Leppard and Rock of Ages: The Definitive Collection released in 2004 and 2005 respectively.In reference to the song, lead singer Elliot said in the album's commentary that Work It Out "was Vivian [Campbell's] first songwriting contribution to the band" and that Elliot "had this opportunity to channel [his] inner Iggy Pop instead of screeching in this high register like [he'd] always done in the past".The music vide
