Seen Whitesnake several time and in my opinion Coverdale is dreadful and the band is just a wall of noise to try and cover up his poor vocals.

Saw Def Leppard last year and they were fantastic. Had seen Joe struggle a few times over the years, but he was spot on. I also think Jovi are going to struggle to follow Leppard as their current A Game is well below Def Leppard's (again in my opinion).
