Yugoslavia "Also Sprach Zarathustra" (single)
This single couples "Also Sprach Zarathustra" with "Polk Salad Annie". The tracks and cover are taken from Volume 31. The cover is of course a miniature of the LP sleeve, and the back is identical to the front. The paper is extremely thin and as a result, susceptible to damage. It is not known whether the LP itself was ever released there - the best we can say is that it's possible.
