Years ago we attended a Tony concert at the outdoor Mann Music Center in Philadelphia, actually in Fairmount Park, not in center city. Diana Krall was his opener, then just starting out. While she was doing her intro, a cell phone rang, she stopped singing or speaking when that happened, and said to the person rather angrily to turn it off, that Mr. Bennett wouldn't like it if that happened while he was performing. That was in the infancy of cell phones, I think there was applause after what she said. And Tony was wonderful in his what I think was sharkskin blue suit, he seemed to like that fabric & color. Truly amazing man !
