While there are other entities named "Umlaut" (bands, film editing companies, etc.), *THIS* Umlaut's favorite *OTHER* Umlaut is George Harrison's Umlaut Corporation.
The Umlaut Corporation is the music publishing arm of his Dark Horse Records, which was the record label Harrison formed in 1974 and oversaw until his death.
Yet another reason why Harrison is my favorite Beatle!
Thanks to Umlaut friend and fellow Music Geek Jim for pointing this out.
