There are zero reliable sources (and I don't mean Youtube and Crawdaddy, they are not reliable) for this. If there's a reliable source for the Def Leppard incident then include that in the article. Personally I can't stand Danzig but that's irrelevant to producing an accurate article sourced reliably and not filled with seedy tabloid garbage. You sound like someone with a bone to pick. If you want gossip and sensational nonsense go read The Sun. Otherwise, nobody cares that "Danny Lollipops" deliberately provoked and then assaulted a singer backstage and then put the video online in hopes someone would listen to their awful band. Considering it was 5 years ago and nobody remembers the shitty band I'd say their ploy failed.
