FILE - In a Tuesday, June 12, 2012 file photo, former President George H.W. Bush, and his wife, former first lady Barbara Bush, arrive for the premiere of HBO's new documentary on his life near the family compound in Kennebunkport, Maine. Bush spokesman Jim McGrath said Wednesday, Dec. 26. 2012 that doctors at the Houston hospital where Bush has been treated for a month remain �cautiously optimistic� that he will recover. Still, no discharge date has been set, and McGrath says that doctors are being cautious because at Bush�s age �sometimes issues crop up that are beyond anybody�s ability to discern or foretell.�(AP Photo/Charles Krupa, File)
Former President George H.W. Bush remains in intensive care at a Houston hospital, but he's improving.
Bush family spokesman Jim McGrath said Friday that the 88-year-old former president is continuing to improve. He says Bush is "alert and, as always, in good spirits."
McGrath says Bush's conversations with doctors and nurses at Methodist Hospital now include singing.
He says physicians remain "cautiously optimistic that the current course of treatment will be effective."
Bush has been hospitalized since Nov. 23. He was moved into intensive care on Sunday for treatment of a fever following a bronchitis-related cough.
