Jimi Jamison, the lead singer for Survivor, has died of a heart attack, according to the group's official Twitter page.

"Survivor is very shocked & saddened by the passing of our brother Jimi Jamison," the tweet read. "Our thoughts, love & prayers go out to his friends & family."

TMZ reports that Jamison died Sunday night and was found dead in his Memphis home around 1 a.m. Monday by his son, according to Survivor's booking agent. He was 63.

Jamison joined Survivor, in 1984, by which point they'd already topped the Billboard Hot 100 with "Eye of the Tiger" and scored a top 20 hit with "American Heartbeat." But his first album, "Vital Signs," produced a string of hits -- "I Can't Hold Back" (No. 13), "High on You" (No. 8) and "The Search is Over" (No. 4). Subsequent hits with Jamison on vocals included "Burning Heart" from the "Rocky IV" soundtrack (No. 2) and "Is This Love" (No. 9).

Prior to joining Survivor, Jamison sang for Target and Cobra. His first recording with Survivor was "The Moment of Truth" from "The Karate Kid." As a solo artist, he co-wrote and sang "I'm Always Here," the theme song for "Baywatch."

Survivor disbanded in 1989, reuniting four years later with the singer Jamison replaced, Dave Bickler, back on vocals. Jamison rejoined twice, from 2000-2006, and then again in 2011. That's Jamison in the classic, Emmy-nominated Starbucks commercial from 2005, singing "Eye of the Tiger."

He played his last Survivor show Saturday night in California.

Survivor were scheduled to appear at Wild Horse Pass Hotel & Casino on Oct. 4. The show has been removed from the Wild Horse Pass' website.
