Back when I first started playing piano back in the '60s, there was a piece of sheet music in the bench, the Star Spangled Banner, simplified arrangement for the piano by Angela Diller (c. 1942 or so). Maybe 10 years ago, it occurred to me that that 'simplified arrangement' was really four voices. (If I had to guess, they'd be bass, contra-bass, tenor & alto. ) With practice, I can sing any of the parts; my fingers have been playing them for 40+ years. It's a wonderful harmony (except for *one* chord near the end). *That's* what I expect to hear when I hear our national anthem.
'Make it your own?' The NFL are wrong. Our national anthem should be performed with due reverence and care. But I guess since the (defunct) republic is a laughing stock, it's only reasonable that 'artists', and all of us, be encouraged to mock the republic at all turns.
We didn't even turn the TV on this weekend. If my eyes hadn't paused on the sports page in passing, I wouldn't know who won.
