The absolute best singing of Our National Anthem I have ever heard was done back in the mid-80’s for the Opening Ceremonies at one of the NASCAR Races at Talladega Superspeedway by an Alabama State Trooper. I can only describe it as PERFECT !!! The lyrics, tone, cadence, presentation- everything !!!
My younger sister is a trained operatic singer. She sings for weddings and funerals. She is 5 foot nothing, but has strong volume and clarity. About 10 years ago, she sang the National Anthem at a Texas Rangers game in Dallas. Our family bought up 2 rows of seats to see that. Very proud moment when I saw my sister on the jumbotron belting out the Anthem with no mistakes.
