The organisers said that Green Day’s set was not curtailed and afterwards Billie Joe was “pumped and laughing backstage”.

Green Day’s website apologised to fans who were offended.

It said: “We would like everyone to know that our set was not cut short.

“We regretfully must postpone some of our upcoming promotional appearances.”
