Jimi Jamison, lead singer for the bands Cobra and Survivor, was found dead Monday morning in his Memphis home.
His booking manager, Sally Irwin, tells TMZ that Jamison apparently died of a heart attack on Sunday night and was found early the next morning by his son. He was 63.
Jamison had performed with a reunited Survivor on Saturday at Morgan Hill's Downtown Amphitheater and on Friday at Reno's Grand Sierra Resort.
Jamison joined Survivor in 1984, after the band found success with "Eye of the Tiger." He was the lead singer on songs including "The Moment of Truth" (from "The Karate Kid"), "The Search Is Over," "Burning Heart" (from "Rocky IV") and "Is This Love."
As a solo performer he was co-writer and vocalist for the "Baywatch" theme song "I'm Always Here."
