That's terrific, gnomad. this page says the melody was by Robert Schumann, Der Schmied, Op 145 No 1. [YouTube Recording]

I found the German text with a side-by-side translation at about.com:

Der Schmied	The Smith
von Ludwig Uhland	Translation by Hyde Flippo
Ich hör' meinen Schatz,	I hear my sweetheart,
Den Hammer er schwinget,	The hammer he swings,
Das rauschet, das klinget,	That whistles, that clangs,
Das dringt in die Weite	That penetrates into the distance
Wie Glockengeläute	Like the peal of bells
Durch Gassen und Platz.	Through streets and square.
Am schwarzen Kamin,	At the black furnace,
Da sitzet mein Lieber,	There sits my love,
Doch geh' ich vorüber,	But if I pass by,
Die Bälge dann sausen,	The bellows then groan,
Die Flammen aufbrausen	The flames roar up
Und lodern um ihn.	And blaze all around him.

Now, can anybody find the complete English text from Singing Together? If somebody can send me a MIDI, I'll post that, too.
