Survivor has had two different lead vocalists twice. I mean to be fair, the original “Eye Of The Tiger” vocalist had health issues to over come and left the band. The “Burning Heart” “I Can’t Hold Back” guy joined and after a few years started a solo career when Survivor began its hiatus and legal sagas. Jimi Jamison was approached to sing with Deep Purple.
Things began to pick up and the original vocalist, Bickler returned to Survivor however after seven years, he was fired from the band. Jamison returned. Jamison left. The band toured with both vocalist for a brief period. Jamison dies. Bickler quits for the last time. It’s all a little Spinal Tap like.
