Not I but our oldest dau went with her school HS choir summer before her Sr yr. I asked her during the Carter funeral if it was at the Nat'l Cathedral they sang, she said, yes and it was beautiful. Another story from that trip is they were walking thru and around the outside of the Jefferson monument, the kids just once broke out in singing God Bless America. It was an acapella choir and I am sure it was touching as the crowd gathered around to listen. A guard asked them if they had a permit, of course they didn't, she asked the to stop singing. Strange but true. This was in 1988.
