Hans Blum is one of the most famous and successful composers, lyricists, and singers for German Schlager. In the late 60s, three of his hits were awarded the "Deutscher Schlagerpreis" (including "Beiß nicht gleich in jeden Apfel" and "Harlekin"). Using the pseudonym Henry Valentino, Blum entered the German charts with songs such as "Ich hab Dein Knie gesehn" and "Im Wagen vor mir" (eight months in the top 50 of German charts).
