Little Girl

It means a half-bottle of wine

"Can I have some of that little girl you have left?"
"No, it's mine and I'm drinking it!"

Well, show me the way
To the next whisky bar
Oh, don't ask why
Oh, don't ask why
Show me the way
To the next whisky bar
Oh, don't ask why
Oh, don't ask why
For if we don't find
The next whisky bar
I tell you we must die
I tell you we must die
I tell you, I tell you
I tell you we must die
Oh, moon of Alabama
We now must say goodbye
We've lost our good old mama
And must have whiskey, oh, you know why
Oh, moon of Alabama
We now must say goodbye
We've lost our good old mama
And must have whisky, oh, you know why, yeah
Well, show me the way
To the next little girl
Oh, don't ask why
Oh, don't ask why
Show me the way
To the next little girl
Oh, don't ask why
Oh, don't ask why
For if we don't find
The next little girl
I tell you we must die
I tell you we must die
I tell you, I tell you
I tell you we must die
Oh, moon of Alabama
We now must say goodbye
We've lost our good old mama
And must have whisky, oh, you know why
