Many people think JJ recorded this song in E, like Eric Clapton, he 
did not. 
Instead, it is in C# 
 
       C# C# B    C#                B                     C# C# B C# B 
If you wanna hang out, youve got to take her out, Cocaine 
 

       C# C# B   C#    B                           C# C# B C# B 
If you wanna get down, down on the ground, Cocaine 
         C#            B             A   Ab 
She dont lie, she dont lie, she dont lie    Cocaine
