Yes, but how do the the sire and dam's names add up to Opry? Sinatra wasn't a country singer, and Declaration of War has no connection to Nashville, country music, the Opry or anything else in that vein. OTOH, there was a 2007 foal also named Opry. Her dam was Acuff -- Roy Acuff was a country music legend and the heart and soul of the Opry.
Put That Voodoo Youdo on the "what?" list, too. She's by Speightstown-Our Friend Terry, by Cox's Ridge. Again, probably the favorite song of someone with a say on the name of the horse, who was probably going to name a horse that regardless of pedigree.
