the most successful of the jacksons' recordings for epic, "shake your body" (originally demoed as "shake a body") was produced by the jackson brothers, written by randy and michael, and featured michael on lead vocals. the chorus "let's dance/let's shout (shout)/shake your body down to the ground" was inspired by an ad-lib from marvin gaye's "got to give it up": "let's dance/let's shout (shout)/gettin' funky's what it's all about" and the rhythmic pattern from teddy pendergrass's "get up, get down, get funky, get loose" (from his album "life is a song worth singing", released a couple of months previously).
