From George H.W. Bush spokesman Jim McGrath:
“President Bush remains in the intensive care unit at Methodist Hospital, where he continues to improve. The President is alert and, as always, in good spirits — and his exchanges with doctors and nurses now include singing. The Bushes thank everyone for their prayers and good wishes and, like their doctors, are cautiously optimistic that the current course of treatment will be effective.”
