of those purely hair metal nostalgia concerts. I took my kids, but the dude sitting next to me had to be in his mid-50s. Whitesnake opened for them, but played for a lot longer than most opening bands.
And FTR, Whitesnake probably got as much crowd participation as Def Leppard especially when they played Here I Go Again and Slide it In. David Coverdale still has a decent set of pipes for someone who was 67 at the time.
