“Curtain Falls" is a single by Blue released in 2004 for the album Best of Blue. This song was produced by Stargate and reached number one in Italy. In France, the song was re-recorded in French and re-titled "Quand Le Rideau Tombe", and thus, this version was released as a single there. The background music is virtually identical to that of Coolio's 1995 hit, "Gangsta's Paradise", as they both share usage of a sample of Stevie Wonder's "Pastime Paradise".
