London - Olympic bosses in London have promised to investigate major sponsors after banks of empty seats were spotted at several sold-out Games venues yesterday. Several high-profile venues, including the Aquatics Centre in the Olympic Park and the gymnastics arena in North Greenwich, had rows of empty seats during morning sessions on the first day of the Games. Locog - London Olympics Organising Committee -  said they would be investigating why the seats were unfilled, while Lord Coe - Locog chairman - has reportedly promised to name and shame sponsors who did not find takers for the venues. Although cheaper seats higher up in the Aquatics Centre were filled to capacity by the general public, those lower down had rows of empty seats for this morning's swimming heats Locog said the seats were meant to be filled by officials and media at the Aquatics Centre. Fans who paid huge sums to secure sought-after Olympics tickets were left fuming as seats - thought to have been bought in bulk by Games sponsors - were left unfilled. At the Aquatics Centre, where every session is a sell-out, there were rows of empty seats in the lower tier, where more expensive tickets are situated. Following the opening of the Games last night, more than a billion worldwide apparently tuned with mixed reactions. Branded an 'anti-climax' With its pastoral scenes, references to James Bond, yellow submarines and Mary Poppins, the spectacular Opening Ceremony was certainly very British. The Queen's cameo appearance was a particular highlight for the non-British audience as she took part in a comical segment filmed in Buckingham Palace with Daniel Craig, before seemingly parachuting into the Olympic Stadium with the James Bond star. But some of the more obscure references left many scratching their heads. The appearance of Mr Bean also got viewers from the other side of the Atlantic chuckling, with Rowan Atkinson's comical character seeming to go down well with the American press. The ceremony's showcasing of Britain's rich musical history was another highlight with the use of songs from UK's finest singers and performers seeming to be a massive hit.(FA/NSN)
