Jazz star Al Jarreau has been transferred by helicopter from a hospital in the French Alps to another in Marseille after he fell ill with breathing problems, which were aggravated by the altitude.
The 70-year-old musician is expected to remain in the cardiology unit of La Timone hospital in Marseille for a week to undergo further testing.
The singer collapsed on Thursday (22Jul10) after fainting moments before he was due to perform at a music festival in Barcelonnette, in the southern French Alps.
He is believed to have had trouble adjusting to the mountain altitude, according to the Associated Press.
Jarreau, who has been touring Europe and Japan, has cancelled a further two shows in Germany and another in Azerbaijan.
