Deepest Purple: The Very Best of Deep Purple is a compilation album by the British hard rock band Deep Purple, released in 1980. It features the original hits of Deep Purple before their 1984 reunion. Aided by a TV advertising campaign it would become Purple's third UK #1 album. It was at one point the longest album ever released as a single LP, but it was overtaken by Def Leppard's Hysteria album in 1987. This also marked the debut of "Demon's Eye" for the North American release, where it was replaced by "Strange Kind of Woman" on Fireball. The film, released on DVD with the 30th anniversary edition, features track by track Jon Lord interviews.
