City Diary: Sitting on the fence overlooking the red carpet In other words: you pay your subs and we'll sit on the fence. Congratulations to Virgin Trains, named Best Train Operator for sixth year running by Business Traveller magazine. The award's sponsor? First Great Western. How ironic. September is one of the busiest months for investment bankers as the City returns from its summer break. Nice to see some of the square mile's finest have found a way to keep themselves amused outside UBS's London headquarters (above). Sometimes things just write themselves: "Singer Bing Crosby's geologist nephew, Howard, a major shareholder in a recent AIM IPO Black Mountain Resources Limited, is on the road in London this week with the board of directors as they 'Look for the Silver Lining" for their silver play in the US. Crosby, with 'Silverbells" on is telling London how they are 'Gonna Build a Mountain" with their near-term production in Idaho and Montana." Glad to see he's not riding on his uncle's coat tails. An apology to my mole in Monte Carlo. Yesterday, we told you how a group of insurance executives were left fuming at recent gathering because the hotel they booked forgot to tell them that its swimming pool and sunbathing area were closed for repair. Unfortunately, we also described our source as "Diary's man without a tan." "I did have a tan," he asks us to point out. It's the only reason I go - apart from the champagne and caviar.
