Crazy by Gnarls Barkley (acoustic)

"Crazy" is the debut single by American soul duo Gnarls Barkley, taken from their 2006 debut album St. Elsewhere. It peaked at number two on the Billboard Hot 100, and topped the charts in the United Kingdom, Denmark, Canada, the Republic of Ireland, New Zealand and other countries.

Musically, "Crazy" was inspired by film scores of Spaghetti Westerns, in particular by the works of Ennio Morricone, who is best known as the composer of Sergio Leone's Dollars Trilogy,[12] but more specifically, the song "Last Men Standing" by Gian Piero Reverberi and Gian Franco Reverberi from the 1968 Spaghetti Western Django, Prepare a Coffin, an unofficial prequel to the better-known Django. "Crazy" not only samples the song, but utilizes the parts of the main melody and chord structure. The original songwriters for "Last Man Standing" are credited by Gnarls Barkley for this song alongside their own credits.[citation needed]

The lyrics for the song developed out of a conversation between Danger Mouse and Green. According to Danger Mouse, "I somehow got off on this tangent about how people won't take an artist seriously unless they're insane... So we started jokingly discussing ways in which we could make people think we were crazy... CeeLo took that conversation and made it into 'Crazy', which we recorded in one take."[13]
