I saw Cornelison's rendition and it was very good. But I was at Super Bowl 25 (Giants-Bills) and it was right after we went into Desert Storm. The security to get into the stadium in Tampa was over the top.(Portents of things to come?) I guess what I'm saying is perhaps you had to be there to appreciate it.
Anyway, this video gives you some of the flavor of the time. I STILL love her singing of the anthem that day.
