Muckrock Michael sez, "Today MuckRock's Mara Berg chronicles the saga of a particular public records request I put in for the following: A copy of the backing track used during Beyonce's Inauguration performance, as well as copies of other backing tracks created in preparation for Inauguration events, whether or not they were actually used. Unfortunately, while we received (some) of the requested documents, two outside legal experts and the U.S. Marines Corps have warned us strongly against publishing what we have. The reason? Copyright."
