Lyric It s Saturday Night

It s Satruday 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 let 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
