Tens of humans are fenced in, under spotlights. They are separated into opposite ends of the cage, in different uniforms; half in orange, half in black.

An official enters, shouts. The scene is tense. He stands between the sides, counts up who’s there. Then blows his kazoo [Ed. Kazoo, are you sure? NS: CORRECT] and the battle begins.

The oranges, that’s Amnesty International UK sporting Close Guantánamo t-shirts, are well-organised and play up to the attention of their watching WAGS [Ed. Wives and girlfriends, really? Not colleagues? WHATEVER]. The blacks, that’s AI International Secretariat in their cumbersome Counter Terror With Justice tops, are a little lost outside the rigid command work structure they’re used to but threaten the CG’s goal several times. It’s end-to-end, high-octane stuff but the ref’s kazoo sounds for a goal-less half-time score.

CTWG’s “Manager” Ghias pulls a few people off at half-time and the team is punished when CG’s forward (Steve?) gets between ‘keeper Javier and defender Mustafa and heads the Control Arms-emblazoned football [Ed. This is AI campaigning going over the top. WHATEVER] into the net. CG tick-off the first milestone of their campaign.

CTWJ press on, come close with a long-range Katyusha from Marek and then have a strong call for a penalty rejected. The ref punctuates CTWJ’s waves forward and CG’s counter-attacks with “last 10 minutes” and “5 minutes to go”.

Entering Crisis mode, CTWJ persuade Ghias to drop his controversial rotation system and put on the strongest side. “2 minutes”, “1 minute”… and then the ball is played diagonally into CG’s penalty area into the path of Neil, who shoots the Control Arms ball into CG’s net and dedicates the goal to imprisoned, rendered German of Syrian origin Muhammad Zammar [Ed. Nice touch].

CTWJ jump up and down like school-kids and Javier runs the length of the field with love in his eyes. The kazoo warbles again; it was the last kick of the game.

And we all went to the pub.

Report back from the “Birthday” demo outside Downing Street yesterday: really good atmosphere with about 50 people making lots of noise, chanting “Bring Binyam home” and “Stop Guantanamo Bay”.

We were singing happy birthday, eating cake and holding posters and banners. There was a good spread of people, from the women in head scarves to men in suits, kids and elderly. Some were in orange jumpsuits, some in Binyam t-shirts.

Passers-by were asked to sign petition to return Binyam to UK, as well as writing a note for him on a birthday card to be sent.
