American Pop

The two dancers in the "Sing, Sing, Sing (With a Swing)" montage are The Nicholas Brothers, Harold Nicholas and Fayard Nicholas. The animators directly rotoscoped their dance from Stormy Weather (1943).

Zalmie and his mother flee the czar in Russia but when they are in the US they speak what some people mistakenly assume is German. They're actually speaking Yiddish, which is similar to German and was the language spoken by Jews in Russia at the time.

Disclaimer before soundtrack listings: The following songs were depicted as being written by fictional characters. The producer would like to thank the true composers.

In some versions of the film, dialog has been redone in at last two scenes, presumably to make points more clear. For example, in Little Pete's first scene, he is asked what his Dad would say about him hanging backstage with a rock band. In one version, Pete says "Nothing. He's dead." In the other version, he instead says "I never met my Dad. He's some kind of mystery" (which serves as a better setup for information learned later) Also, Tony returns to the band's apartment after his release from the hospital, only to find they have moved out. In both versions, under 'People Are Strange,' we hear him on the phone with a friend, but the phone conversations begin completely differently. In one we never learn what happened to the band, only that they seemed to have moved out and left Tony behind, while in the other we learn that the band has gone on to big things, with a gold album. Both versions' phone calls end the same way, though, with Tony desperately asking his friend for money or drugs.
