My oldest grandson enchanted my extended family when he was younger by singing "I Am A Child Of God". He was about 3 and it was brand new to them. The sound of a child singing is a beautiful thing, even if it isn't perfect. Of course, my grandson sounded perfect, but I don't have him recorded.
I found this little angel though. She's not singing "I Am A Child Of God", but she is singing my absolute favorite arrangement of "The Lord's Prayer".
