After I put this collection together I thought of that old song "Am I Blue" written by Hoagy Carmichael. There is a scene in the classic film "To Have and Have Not", where Lauren Bacall and Hoagy Carmichael sing this song while Humphrey Bogart looks on. It's a short scene, but I love the way they sing together:
Am I blue, am I blue
Ain't these tears in my eyes tellin you
How can you ask me am I blue
Why, wouldn't you be too
If each plan with your manDone fell through
