Lyrics of 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 let me walk straight, don't let me feel pain
I'm gonna scratch cars with my key again
'cos when i go home and fall on my bed
If it doesn't leave my stomach, it'll split my head

'cos when i go home and fall on my bed
If it doesn't leave my stomach, it'll split my head

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
