An entirely orchestral version of the album was commissioned and briefly released, on August 7, 1967, by Capitol Records in the 4-track Stereo-Pak format only and then withdrawn due to a lawsuit from MGM Records. MGM claimed that the album violated Zappa's contract with their subsidiary, Verve Records. In 1968 it was reedited and released by Verve on May 13, 1968. The new album consisted of two musique concrète pieces that combined elements from the original orchestral performance with elements of surf music and spoken word. It was praised for its music and editing.

Produced simultaneously with We're Only in It for the Money, Zappa saw Lumpy Gravy as the second part of a conceptual continuity that later included his final album, Civilization Phaze III.

Is this Phase Two of WE'RE ONLY IN IT FOR THE MONEY? Is this "a curiously inconsistent piece which started out to be a ballet, but probably didn't make it?" Well, it's FZ's first orchestral composition album, recorded with a 50-piece orchestra and a few stray Mothers, and the birthplace of "conceptual continuity." The musical themes serve as a starting point for future work. Includes career guidance and secret clues from the voices inside the piano. LUMPY GRAVY has been restored to its original 1968 mix; sounding just like it did then -- but better, of course.
