With Dio at the helm, the band had a darker and less melodic edge. They didn't score a chart hit until a new lead singer came aboard (Graham Bonnet), taking the Russ Ballard song "Since You Been Gone" to #57 in 1979. With the change to Joe Lynn Turner, the band scored their only top 40 hit: "Stone Cold" landed at #40 in 1982. Turner would produce one final charting single for the group when "Street Of Dreams" peaked at #60 in 1983.
"Power" comes from the Turner led album from 1982 called "Straight Between The Eyes."
