Really this song is older than the 70's... I've heard blue's players playing it here in Mississippi....
"No point in linking to Led Zep; their songs are not available on iTunes. But they deserve credit for bringing back a great blues tune by one of the first people, man or woman, to electrify the guitar, Memphis Minnie, who wrote this song with her husband after the Great Mississippi Flood of 1927. The lyrics (somewhat reshaped by Led Zep) stand the test of time as well as can be imagined..." (thanks to google....wink) but you "can" hear Led Zeppelin's version.............
If it keeps on rainin’, levee’s goin’ to break,
If it keeps on rainin’, levee’s goin’ to break,
When the levee breaks I’ll have no place to stay.
Mean old levee taught me to weep and moan,
Lord, mean old levee taught me to weep and moan,
Got what it takes to make a mountain man leave his home,
Oh, well, oh, well, oh, well.
Don’t it make you feel bad
When you’re tryin’ to find your way home,
You don’t know which way to go?
If you’re goin’ down south
They go no work to do,
If you don’t know about chicago.
Cryin’ won’t help you, prayin’ won’t do you no good,
Now, cryin’ won’t help you, prayin’ won’t do you no good,
When the levee breaks, mama, you got to move.
All last night sat on the levee and moaned,
All last night sat on the levee and moaned,
Thinkin’ ’bout me baby and my happy home.
Going, go’n’ to chicago,
Go’n’ to chicago,
Sorry but I can’t take you.
Going down, going down now, going down.
