Originals: For The Sake of The Children by Henry Gibson (covered by Cagney and Lacee)
This is a song from Robert Altman's rather splendid film Nashville (there'll be another later in the series). The only clip I can find on Youtube is this one, out of synch and subtitled in Spanish (you could however watch the whole film (with the director's audio commentary) there!). It's performed by Henry Gibson
And yes, it's that Henry Gibson... the Laugh In poet...
... and leader of the Illinois Nazis (in Blues Brothers)
Cagney & Lacee's cover turned up on Six Feet of Chain
