Ill Wind may be found in The Songs of Michael Flanders & Donald Swann and is another magical piece by Flanders & Swann that Dr. Rosteck and I have performed it publicly on a few occasions. It is all about a lost French horn set to the rondo sections of Wolfgang A. Mozart's 4th Horn Concerto in Eb KV 495.
It has an unforgettable line:
I've lost that horn, lost that horn, found that horn .... GORN,
It is said that Michael Flanders actually had his French horn stolen!
