tell me what is happening here

did the rock star provoke the violence?
did the bouncer have just cause to beat his employer?
did the rocker have the right to hit the bouncer?
did the rocker not know that the bouncer was helping?
are drugs, ultimately, to blame?
is this proof that we cant all get along?
how did grohl know so quickly that kurdt was in need?
is that courtney in the pit trying to kill her man?
is this proof that stage diving with a guitar isnt a good idea?
whats the song?
