Quoted: You all have heard Gnarles Barkley's "Crazy" (it's pretty much impossible to get away from at this point), but have you heard "Nel Cimitero Di Tucson", which is essentially a raw instrumental form of Crazy. Unless you check alot of random world-music blogs (like me) you probably haven't. It seems that Gnarles Barkley heavily sampled the song, which comes from the soundtrack of the film, Preparati la bara! (IMDB link here).

It's very interesting to listen to the original version and be able to hear the progression to it's current chart-topping form, most noticeably the trumpets from the original were replaced with strings for Gnarles Barkley's version, but the bass line stays the same nearly the whole song though.
