AC/DC Downpayment Blues lyrics

I know that ????
I know that it got to be
No I ain't doin' much
Doin' nothing means a lot to me
Living on a shoe-string
A fifty cent millionaire
Open to charity
Rock'n'roll the welfare
Sittin' in a Cadillac
Listenin' to the radio
Suzy baby get on in
Tells me where she wanna go
I'm livin' in a nightmare
She's nothing but a wet dream
I've got myself a Cadillac
But I can't afford the gasoline
I got holes in my shoes
And I'm way over due
Downpayment blues
Get myself a steady job
Some responsibility

Can't even feed my cat
On social security
Hiding from the rent man
Oh, they make me wanna cry
Sherrif knockin on my door
Ain't it funny how the time flies
Sitting (on the seventh floor?)
Sippin' off the champagne
Suzy baby ????
Says she wants a cup of gin
Feelin' like a ????
????
Got myself a sailing boat
But I can't afford the ????
I got holes in my shoes
(And I'm way over too)
