I was watching that, it struck me as odd. I wasn’t paying that much attention, but I did think, “wait a minute, he doesn’t even have an accent, why are they playing the Mexican National Anthem?”
On the other hand, the guys who performed the Mexican National Anthem played it straight, and respectful. The bimbo who did the American National Anthem was awful, why couldn’t she just sing it straight? The last fight I saw, Tom Jones sang the Welsh National Anthem, he sang it great (and if anyone could mess with it, he could have) but whoever sang ours was once again awful. It’s not that, as some profess, our anthem is hard to sing - it is, BUT - this is about people who choose to mess it up and make it awful. Just sing it, that’s all.
Agree completely — our own anthem is mangled more often than not at sporting events these days. Improvisation is great for jazz, but it doesn’t work for the national anthem.
