Songtext von Tema de Encerramento (inglês)

Come and join us in a melody, A song of happiness for you and me. Sing of joy, sing about a boy, Little hero, Astroboy! Come and join us in a fantasy, We can all be heros, you and me. Sing of joy, sing about a boy, Little hero, Astroboy! Lighting up the way for all, For soon he will fight for right, Strong as steel and with a heart of gold. Sing of glory, Pour your heart our, Your voices will be heard, And it's raining out with love for all.
