If it keeps on rainin'...

...the levee's going to break...

Interesting story behind the Led Zeppelin tune, "When the Levee Breaks," if Wikipedia is to be believed:

http://en.wikipedia.org/wiki/When_the_Levee_Breaks

"When the Levee Breaks" is a blues song written and first recorded by husband and wife Kansas Joe McCoy and Memphis Minnie in 1929. The song is in reaction to the upheaval caused by the Great Mississippi Flood of 1927.
...
The song was recorded at a different tempo, then slowed down. Plant then sang in the sort-of-in-between key the song was now in (approximately F minor), which explains its sort of flat and sludgy sound, particularly on the harmonica and guitar solos. Because this song was heavily produced in the studio, it was difficult to recreate live. The band only played this song a few times in the early stages of their 1975 U.S. Tour.

Anyway, so far it doesn't look like a repeat of Katrina. Still, I continue to question the wisdom of living below sea level, unless of course it's in a self-contained continental shelf habitat.

Now that would be cool.
