Jimi Jamison, the former lead singer of Survivor and the man behind the hits "Burning Heart" and The Karate Kid's "The Moment of Truth," died Sunday, August 31.
He was 63.
"The entire Survivor family is very shocked and saddened by the passing of our brother Jimi Jamison. Our thoughts, love and prayers go out to his family and friends," the band's official Facebook page posted Monday.
His booking agent Sally Irwin told the Los Angeles Times that he died of a heart attack at his home in Memphis, Tennessee.
Jamison joined Survivor after their most famous hit "Eye of the Tiger," when original lead singer David Bickler left for medical reasons. He also co-wrote and sang the Baywatch theme song "I'm Always Here."
