PARIS (REUTERS).- Thousands of art lovers queued in freezing temperatures on Saturday night for a final glimpse of a major retrospective on French Impressionist Claude Monet, after Paris’ Grand Palais opened round the clock to cope with demand. Wrapped in scarves and heavy coats, people queued for more than three hours to see the nearly 200 works by the 19th century master before the historic exhibition, the biggest one on Monet in decades, closes on Monday evening. Staff from the museum brought hot drinks and slices of cake to keep up their spirits, and a clarinetist serenaded the shivering crowds. Jean-Paul Cluzel, chairman of the Grand Palais, said the museum had decided to keep its doors open continuously from Friday to cope with the record number of visitors, expected to total nearly 1 million since the exhibition opened in late September. “The three nights add up to 40,000 more visitors,” Cluzel told Reuter
