This long piano section, which follows straight on from "United States of Eurasia," is an altered version of Frédéric Chopin's Nocturne in E-flat Major Op. 9 No. 2, with additional sounds of playing children, and the sound of warfare. Singer Matt Bellamy performed the piece and he described it to MTV News as, "this weird piano part with the sound of innocent kids and warfare and stuff, which is kind of the aftermath that happens after all this grad strategizing."
Nocturne in E-flat Major was one of a set of three nocturnes written by Polish composer Frédéric Chopin between 1830 and 1832 when he was in his early twenties. Chopin composed no fewer than 21 nocturnes in total. They sound effortless, but he would often spend days agonising over just a few bars.
"The Night Chicago Died" was written and recorded by the British group Paper Lace. They talk about Al Capone in the song, but got a lot of details wrong - understandable since they wrote it based on gangster movies.
"Cruise" climbed from 6-5 on the Hot 100 in its 34th week. In doing so it set a record for the slowest ascent to the Top 5 in the chart's history, which was beaten by Imagine Dragon's "Radioactive" 42-week clamber to #4 three weeks later.
