It's Saturday Night

It's saturday night, I'm feeling on song
I think I'm alright, I know I'm all wrong
The drink that I had three hours ago
Has been joined by fourteen others
In a steady flow

So lot me walk straight, don't let me feel pain
I'm gonna scratch cars, with my keys again
Cos when I go home and fall on my bed
If it doesn't leave my stomach, it'll split my head.
