Apparently, the translation was farmed out to the same firm that prepares instruction manuals for Japanese-made products, or perhaps by the man who wrote "English as She Is Spoke".

I have a copy of the Seraphim LP. I'd ask you to PM, but at the moment that option's not available. So here are two alternatives: if you have a (temporary?) email address you don't mind posting here--with username and site well separated by verbiage to foil addy-collecting bots. Alternatively, if you have either Kat's or Joe's email address, perhaps they wouldn't mind forwarding an initial email from you. Just tell me which you'll be sending the message to, and I'll shoot them a note so they'll know where to send your message. Make sure to include the URL for this thread.

I think you'll find most of the lyrics (often with translations) through this page:
The Lied, Art Song, and Choral Texts Archive: Wolfie
http://www.recmusic.org/lieder/m/mozart/

For PDF scores and MIDIs, try WIMA: Werner Icking Music Archive: Wolfie
http://icking-music-archive.org/ByComposer/Mozart.php

Other sites, on a hit-and-miss basis, provide full or partial translations, though I can provide the ones from the LP.

Isn't it criminal that, when reissuing CD's, they often omit the original materials. After all, they could just scan the info and include the images as additional files on the CD itself, at virtually no additional cost!
