Tomorrow Belongs to Me was written by John Kander and Fred Ebb as a pastiche of the rousing German patriotic songs of the period (Die Wacht am Rhein and the Horst Wessel Lied, for instance). Sung by a stereotypical Hitler Youth, it often has been mistaken for genuine. This has led to the songwriters (both Jewish, incidentally) being accused of anti-Semitism.
