It's getting late have you seen my mates
Ma tell me when the boys get here
It's seven o'clock and I want to rock
Want to get a belly full of beer
My old man's drunker than a barrel full of monkeys
And my old lady she don't care
My sister looks cute in her braces and boots
A handful of grease in her hair
chorus
Don't give us none of your aggravation
We had it with your discipline
Saturday night's alright for fighting
Get a little action in

Get about as oiled as a diesel train
Gonna set this dance alight
'Cause Saturday night's the night I like
Saturday night's alright, alright, alright
Well they're packed pretty tight in here tonight
I'm looking for a dolly who'll see me right
I may use a little muscle to get what I need
I may sink a little drink and shout out "She's with me!"
A couple of the sound that I really like
Are the sounds of a switchblade and a motorbike
I'm a juvenile product of the working class
Whose best friend floats in the bottom of a glass
[repeat chorus]
[repeat chorus]
