Cool water is an old country song.
Black Rebel Motorcycle Club covered the Hank Williams version.
Here are the chords.

Normal Tuning EADGBe

C                      G7
All day I've faced the barren waste 
    C                 G7             C     
Without the taste of water..... cool water
    F              G7        
Ole Dan and I with throats burned dry
    C          F       C         G7          C
and souls that cry for water.... cool, clear water

                         G7     
The nights are cool and I'm a fool
     C                 G7              C     
Each star's a pool of water.... cool, water
    F                  G7                    
And with the dawn I'll wake and yawn
    C     F     C         G7          C                      
and carry on to water.... cool, clear water

                     G7     
The shadows sway and seem to say
  C                 G7              C                
Tonight we pray for water.... cool, water
    F                  G7                         
And way up there He'll hear our prayer
    C       F             C         G7          C                          
and show us where there's water.... cool, clear water

                            G7                     
Keep a movin' Dan don't you listen to him Dan
         C                   G7                            C                   
He's the devil, not a man he spreads the burnin' sand with water
F                      G7                      
Dan can't you see that big green tree
          F                          G7                        C                
where the water's runnin' free, it's waiting there for you and me
G7              C                     
water.... cool, water

                         G7                
Dan's feet are sore he's yearnin' for
     C                   G7              C                    
Just one thing more than water.... cool, water
     F               G7                 
Like me I guess he'd like to rest 
      C          F         C         G7          C                              
Where there's no quest for water.... cool, clear water
