Lyrics:

[WAGSTAFF]
I don't know what they have to say
It makes no difference anyway
Whatever it is, I'm against it
No matter what it is or who commenced it
I'm against it

Your proposition may be good
But let's have one thing understood:
Whatever it is, I'm against it
And even when you've changed it or condensed it
I'm against it

I'm opposed to it
On general principles, I'm opposed to it

[STUDENTS]
He's opposed to it
In fact, indeed, he's opposed to it

[WAGSTAFF]
For months before my son was born
I used to yell from night till morn
'Whatever it is, I'm against it.'
And I've been yelling since I first commenced it
I'm against it
