 Several songs are credited to the New York punk/Gypsy/Jewish klezmer band, Gogol Bordello, which is led by Eugene Hutz, who plays Alex in the film (the same band greets Jonathan when he arrives on the train). The last of these songs, "Start Wearing Purple (For Me Now)," which plays over the end credits, is credited to both a correct spelling (Gogol Bordello), dg and Gogol Bodello, an incorrect spelling.
