Man Whistles National Anthem at Orioles Game

There have been thousands of renditions of the national anthem performed before sporting events over many decades.  Sometimes it’s an individual singer.  Sometimes it’s a small group.  Sometimes it’s a brass band.  It’s been guitarists, trumpeters, pianists and several other instrumentalists. In Baltimore, though, they trotted out a world champion whistler.  Is he good?  You decide!
