Although she did also mention she thought President Bush (I'm not sure she was that respectful) did well.
Also, people shouldn't put much into whether someone sings etc. or not. Everyone handles grief in their own way.
I don't know if it has been mentioned, but Scott Baio was at the interment service. I don't know his connection to the Reagan family, but he looked very respectful and saddened when he passed by the coffin.
He always seemed like a good egg, so it's good to see that he is.
