This Gorillaz track, featuring Detroit rap group D12 and The Specials singer Terry Hall, was recorded right after 9/11 when D12 was stuck in Britain and they came across the Gorillaz. Hence the name of the song.
Damon Albarn and Terry Hall had previously spoken about collaborating together, and since Albarn had been wanting to experiment with Middle Eastern music, they decided on this track, inspiring Albarn to take it in a different direction. D12 was stranded in England after the 911 attacks. Damon Albarn invited the band back to his studio to listen to an early version of the song, they added additional production to the song, then laid down their verses.
