I used to lead a group that sang "carols" for Fourth of July and Christmas in various nursing homes in town. I think we sang at 14 nursing homes at most. I remember visiting a memory care home one Fourth of July. At the start of our performance, I announced, "Ladies and Gentlemen, our National Anthem. I was dumbstruck to see all those people stand up, place their hands on their hearts, and sing the Star Spangled Banner with us. They knew all the words, and sang with gusto. I was almost in tears.
