As mentioned way above, I saw them in 77 at Soldier Field, Chicago in their prime.
I think it was in the 90s (could be wrong on yr), when they reformed with Johnny singing, I worked with them. I didn't mix.
But I just don't care for Johnny, he's exaggerating the role.
He was a pretty boy type in the late 70s-90s. His music sucked. He would have never fit the band. Suddenly over-night he took on this tough biker type roll, which LS was never about. And his vocals, IMO just aren't there.
I worked with 38 Special where the youngest Donny VanZant sang some. He came closer to the Ronnie image. He was actually a lil bit more rowdy than Ronnie, who just stalked the stage.
ANYWAY, I still get in a old skewl LS mood once in a while.
