A la Nanita Nana, is an eighteenth-century Spanish Christmas carol here performed by the chorus of U.S. Army Band "Pershing's Own", led by Colonel Thomas Rotondi, Jr. (Leader & Commander) and CSM Debra L. McGarity (Command Sergeant Major) c. 2010. It is done bilingually, first in Spanish, then in English. The English translation appears to have been done in house by the Army, as I can find no evidence of any other usage. CSM Debra L. McGarity
