Composer credits on the B-side (Schubart, Schubert) are no misspelling. The original lyrics of "Die Forelle" (meaning "The Trout"), one of Franz Schubert's most popular songs ("Lieder"), were written as a poem by Christian Friedrich Daniel Schubart in 1782. Schubert set music to the poem in 1817. The song was so popular that Schubert composed a piece of chamber music based on the song, the "Forellenquintett" (Trout Quintet), with variations of "Die Forelle" in the fourth movement.
