This stomp features Atlanta-based rapper Pill and the London Gay Men's Chorus. Backing vocals are by Ronson's long-time collaborator Alex Greenwald of Phantom Planet, who previously featured on the Rehab producer's version of Radiohead's 'Just'.
Ronson said to Spinmagazine of the London Gay Men's Chorus' contribution: "I wanted the song with the choir to sound like Roland Emmerich–2012-s--t-blowing-up-in-the-background. And those guys came in, and they just rocked it."
The title is a reference to the name Mark Ronson and the Business Intl, which the producer started recording as for the Record Collection album. "The Business" is British slang meaning "The Best."
When "Nothin' On You" reached #1 on the Hot 100, B.o.B became the first American act whose name is a palindrome to top the chart. The other two who did so prior to the Atlanta rapper were both Scandinavian groups - ABBA and A-Ha.
"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.
