VERSE 1
C		 		G			Am			      F
Now after all this time			your standing at my door
C				  G			Am				F
Just when I cleared my mind     	your coming back for more
C					G		Am			  F
Well it doesn't work that way   	you see I'm over you
C			       		G  	F		    		C
And now,there's nothin left to say 	just find someone new

********************     Chorus    *****************************
G			       	Am			  C	
40 days and 40 nights	 the rain came pouring down
G			      	Am		 	F
40 day and 40 nights 	no dry land to be found 
G		    	 		F		C	AM
Torrents of rushing water, birds in endless flight
G			D		C   F		   Am		C	
Your nowhere to found,  	40 days and nights
***************************************************************
VERSE 2
Oh I, remember when                everything was fine
When I look back again             they were such happy times
But you,  had to go and change     made everybody blue
Now the stories been rearranged    so find someone new

************************* repeat chorus
