e.g. Rammstein have been refused on safety grounds before now.
2001: "Rammstein were unable to play their show yesterday at the Astoria in London due to significant restrictions to their stageshow and pyrotechnics. The band feel it would be unfair to their fans, to see a show that would have become highly compromised. If these issues can be resolved the band promises to return to the UK later in the year for live shows. Rammstein apologize for letting their fans down due to a problem which was out of their hands"

That's entirely irrelevant to this discussion.
It was relevant to its parent comment about venues being perfectly able to refuse Rammstein for whatever legal reasons they wanted.
