Making women swoon with his good looks and soulful voice, Bolton was a major pop star in the 1980s and '90s, winning Grammys and selling millions of records. In the '70s, Bolton was the singer for the hard rock band Blackjack, which also featured future members of Kiss and the Pat Travers Band, but he didn't break through until going solo. His outsized pop versions of soul hits like "Dock of the Bay" scored big with boomers and youngsters alike.
