Iron Maiden frontman Bruce Dickinson branded the Norway killer an "a--hole" on stage in London last Friday.
They were on stage at the O2 Arena when Bruce gave a speech about how Maiden fans are united, no matter where they're from or who they are - unless they're an evil extremist.
"There's something [in our music and message] that unites people, and it doesn't matter what color they are or what religion they are, or whether they are male or female or somewhere in between."
"We were in Belfast the other night [where you hear] all the bullsh-t about Protestant, Catholic, this and that and the other. And I just said, 'Look, this is a safe house, this is our house, this is Maiden's house, everybody's f--king welcome and we don't turn anybody away, no matter who they are."
"Except maybe... We were in Oslo the other week [where] the most recent, bullsh-t, appalling atrocity wasn't committed by a Muslim, it was committed by somebody who called themselves a Christian - the a--hole over there, really. Unbelievable."
