LONDON: The gravelly tone that made Bonnie Tyler's singing instantly recognisable was the result of an accident.After an operation to remove vocal cord nodules in 1977, she was ordered to rest her voice. But one day she screamed in anger, permanently altering it.Six years on, the Welsh singer would release her best-known song, Total Eclipse of the Heart, which flaunted her husky sound and was nominated for a Grammy Award.Holding Out for a Hero, another dramatic rock ballad, was released soon after, helping Tyler make her mark on Britain's pop scene. Both recordings have since featured in films, television shows and advertisements.Tyler, whose releases also included It's a Heartache and Lost in France, has died, BBC News reported on Thursday (Jul 9). She was 75."I WOULDN'T SAY BOO TO A GOOS
