LONDON, Nov 26: The Rolling Stones turned back the clock in style yesterday with their first concert in five years, strutting and swaggering their way through hit after familiar hit to celebrate 50 years in business. Before a packed crowd of 20,000 at London’s O2 Arena, they banished doubts that age may have slowed down one of the world’s greatest rock and roll bands, as lead singer Mick Jagger launched into “I Wanna Be Your Man”.
