So many people piped up their astonishment on Twitter that a Tumblr was called for:
Then the daily minstrel rockcookiebottom turned his talents to telling the story of Arcade Fire winning the now infamous gong and attempting to explain who the band actually were.
Then it got ugly, with reports of rampaging vigilante hipsters terrorising the streets and wreaking their hip vengeance on all who profess ignorance of the band.
It is hoped that the hipster value of Arcade Fire will have waned significantly since their like, totally lame sellout Grammy win, and the violence should come to a natural end as hipsters find more obscure bands to support.
Stay tuned to teh Pony for updates as they develop.
