By MARK KENNEDY, Associated Press Bonnie Tyler, the gravelly voiced, Grammy-nominated Welsh pop star best known for singing the chart-topping power ballad “Total Eclipse of the Heart” in 1983, and seeing new generations succumb to its bombastic charms during solar and lunar eclipses, has died. She was 75. Tyler died unexpectedly in a hospital in Portugal where she was being treated for an illness, her family said Thursday in a statement on her website.
