One of my favorite songs to this day, The Day The Rains Came performed by Jane Morgan. The qualifying reference is in the second line:
The day the rains came,
Mother Earth smiled.
I was going to post a very poor copy of the song being performed by Jane with Louis Armstrong and Les Brown and his band of renown but the video and sound quality is too poor; great performance though.
I think you guys left the easy one for me, The Planets suite by Holst. If you have an hour or so, enjoy: Mars, Venus, Mercury, Jupitor, Saturn, Uranus, and Neptune.
