Ok. Then that's who I saw sing with Yngwie the two times I saw him in 1985. I've seen pics of JSS and there's no way that's the same guy.
I did do a Image search for Boals and among the pics was that one. It's funny because the first time I saw Yngwie, we were in the 5th row, and I was like, who is this midget singing for him?
And I also want to say that JSS' performance on Marching Out is one of my all time favorite vocals.
