Uh...it's not a cover. Keith Morris wrote the lyrics and the "melody" (if I can call it that)to the Black Flag song "Wasted", with Greg Ginn supplying the music in his trademark writing style of the time (which was generally more dark and dissonant than other punk bands of the era, including the later-to-be-formed Circle Jerks). When Keith Morris jumped ship and started Circle Jerks, he wanted to keep this song and "I Don't Care" because he had at least a 50% songwriting investment in those songs. So he kept his words and probably Greg Hetson wrote new music, thus creating a "new" song with the same title, words, and one shared co-creator.
