I'm a fan of the traditional anthem especially when done in public or special event. I've heard it butchered enough over the years to make my head spin. Some just aren't top-notch singers and neither am I so I give them an A for effort. Rosie had to be the most disrespectful ever. That was just junk.
I want to hear the real anthem at events but this one made me smile a bit. (I'm a metal junkie)
