Treason? Truculence?

I went to a memorial service in Balboa Park yesterday afternoon. I felt patriotic and solemn, and I felt myself tearing up in the car as I was driving down, just thinking about hearing the national anthem being played. I was disappointed though -- both in the events and in myself -- because the guest singers kept screwing up the lyrics to songs like "Let There Be Peace on Earth" and "God Bless America." I'm hopelessly nitpicky, I think.
