A classical concert featuring pop pianist BEN FOLDS was thrown into chaos last night (09May07) when two members of the audience started fighting. Folds and conductor Keith Lockhart were among those stunned by the fracas at Boston, Massachusetts' Symphony Hall. Two men appeared to be fighting in a balcony at the venue, prompting audience members to start screaming and shouting. The conductor briefly halted the performance, which featured Folds, while security staff at the venue escorted the men outside. Police have confirmed the fighting men were escorted off the property. No charges were filed and no injuries were reported. After a brief stoppage, the concert continued.
