Jimi Jamison, Lead Singer of '80s Hitmakers Survivor, Dead at 63 (http://www.people.com/article/jimi-jamison-survivor-lead-singer-dies-heart-attack)
I just heard about this now. I was a fan of Survivor, with both singers. I never had a problem with Jimi stepping in. He has/had a great voice and I enjoyed a lot of of what he did with the band. RIP Jimi.
