This video is taken from Part of the Game website, something which Carlsberg launched and hailed as “probably the best online TV channel celebrating football”. It claims it is “Carlsberg’s tribute to all the people putting their love of football in to play in the stands, in the pub and at home.”
Here is the link to the video on the Part of the Game Youtube channel.
After contacting Part of the Game website, they were quick to respond: Not being English we wouldn’t have found out about the meaning of the chanting otherwise as it occurs in the background of an interview and is difficult for us to understand. I’m obviously very sorry about this and totally agree with your views. We were not aware of the chanting and I deeply regret any offence it might have caused.
