Queen's 1981 promo video compilation Greatest Flix was perhaps the very first of these collections to be assembled by any artist (and subsequently copied by others over the years). Containing a total of 18 clips, Greatest Flix was eventually replaced with the Greatest Hits video in the U.S. 11 years later. Still, the original contained a few clips that haven't been reissued elsewhere, such as "Spread Your Wings," "Love of My Life," "Flash's Theme," and a version of "Killer Queen" that is different than the one on Greatest Hits. Included is one of rock's very first promo clips, "Bohemian Rhapsody," as well as additional classics -- "We Will Rock You," "You're My Best Friend," "Another One Bites the Dust," "Don't Stop Me Know," among others. Released in conjunction with the album Greatest Hits and the photo book Greatest Pix, Greatest Flix has proven to be one of the more memorable and significant music home videos ever released.
