The 24-hour city is already a reality for art-lover Lou Reed. Reed was dining with a friend - the Austrian artist Gottfried Helnwein - on Sunday night, when he decided he wanted to see Helnwein's new show at the Robert Sandelson Gallery. "I had just taken to my bed when I got a phone call from Gottfried", says Sandelson. "But I'm an old fan of Lou Reed so I went as I was and opened up at midnight." For nearly an hour, Sandelson stood in his nightwear and "yawned away while they analysed the pictures in detail".
