Final Fantasy's Owen Pallett, who has arranged strings for the Arcade Fire, orchestrated the tracks on the album. The London Metropolitan Orchestra recorded them over Christmas 2007. Alex Turner was particularly impressed by the work of Pallet on this track. He told the NME: "There's a song called 'Meeting Place' that he really brought to life. When we were recording in France we did come up with some lines, just as initial ideas to send to him. They were quite basic, but he built on that and then he came over for three days in December to record them. We all got together in this hotel room and went through it all. He hasn't worked on too many albums before. He's our age and I think he did a bit on the second Arcade Fire record 'Funeral' and 'Neon Bible' and used to play with them, but I think he was inexperienced enough to have so much excitement for the songs. He know when to leave it out - if it was on all the songs it would be bad - but he knew when we really needed something extra."
Owen Pallet explained to Drowned In Sound about how he came to work on the album: "Laurence Bell from Domino Records contacted me and asked me if I'd meet Alex in Toronto. Alex and I met in the bar of his hotel, he bought me a cappuccino, then we took a cab to my southern Toronto prison and we listened to some David Axelrod records and talked about music. I listened to the tracks he'd recorded, and told him my ideas, and then I scored it out in a couple of weeks, I flew to London and conducted it with an orchestra. It was the most effortless project I've ever worked on."
Kid Rock's "All Summer Long" is a mashup of "Werewolves Of London" and "Sweet Home Alabama." The album it came from was released in October, 2007, but they held off until summer, 2008 for a more seasonable release.
