Seems odd that the performance is marked as PD- maybe because it's a Government-related organization. Asking the person who made the edit. Eric 18:33, 18 September 2010 (UTC)
- It's public domain in the US only (because it's in effect a government publication, as you say), and really should be marked as CC. While it's almost certainly OK in other countries as well, it is not actually public domain outside of the US. KGill talk email 20:06, 18 September 2010 (UTC)
