"Blue skies smiling at me,
Nothing but blue skies do I see.
Bluebirds singing a song;
Nothing but bluebirds all day long.
Never saw the sun shining so bright.
Never saw things going so right.
Noticing the days hurrying by;
When you're in love, my how they fly.
Blue days, all of them gone.
Nothing but blue skies from now on." (Irving Berlin)
