From the 12" single of Primal Scream's If They Move, Kill 'Em this is the 12" Disco Mix, a lengthy mixture of funky drums, noise, guitars, other noises, and that Wild Bunch sample. I don't know what disco this would be played in though.
In a magazine interview recently Mary Ann Hobbs referred to a Weatherall remix of this song, released for one day only. I can't find any other reference to such a remix. Anyone?
