I finally got the lyrics for one of the songs by The Johnstones. It's "Gettin' Payed".
I'll post them here:

We got payed!
I said we're eatin' loin sandwiches, nail it to our eyelids
We got payed!
The check's in the mail and the money's comin' home
We got payed!
Higher tax bracket for playin' this racket
We got payed!

Oh, in my face and I don't care
I don't care what the people say (about me)
It's more than one dollar, more than a dollar
I don't care what the people say (about me)
It'll happen fast, change your life, you're a new guy
I don't care what the people say (about me)
Oh, in my face and I don't care
I don't care what the people say
I said I'm walkin' down the street on a Saturday night
I said I'm walkin' down the street and everything's alright
Oh, I don't care what the people say about me
I said I'm walkin' down the street on a Saturday night
I said I don't care what the people say about me
I don't care what the people say-

We got payed!
I said we're eatin' loin sandwiches, nail it to our eyelids
We got payed!
The check's in the mail and the money's comin' home
We got payed!
Higher tax bracket for playin' this racket
We got payed!

Oh, in my face and I don't care
I don't care what the people say (about me)
Oh, I got monkey butlers and gold plated cutlery
I don't care what the people say (about me)
We're not really rich, we're just jokin' about it
I don't care what the people say (about me)
Oh, in my face and I don't care
I don't care what the people say
I said I'm walkin' down the street on a Saturday night
I said I'm walkin' down the street and everything's alright
Oh, I don't care what the people say about me
I said I'm walkin' down the street on a Saturday night
I said I don't care what the people say about me
Oh, I don't care what the people say about me!

Oh, in my face and I don't care
I don't care what the people say (we got payed!)
I got monkey butlers and gold plated cutlery
I don't care what the people say (we got payed!)
We're not really rich, we're just jokin' about it
I don't care what the people say (we got payed!)
Oh, in my face and I don't care
Oh, I don't care!

We got payed!
We'll be rich, like Richy Rich
We got payed!
We want it all, we want it all!
We got payed!
(Talkin' 'bout) skills, bills, and Rita McNeils!
We got payed!
Let's rock

If you need the song, I've posted it in my podcasts.
