"Introduction (southpaw)" by Gilbert O'Sullivan

Well, before we go any further, we agree
It's a pleasure to introduce Gilbert's L.P.
It's a pleasure of course providing we are paid
If not, we think it's the worst one he has made

Well, before I go any further let me say
That as far as I'm concerned you will be paid
And as Stanley said when he saw Livingstone
I presume the opening tune's
You got me going...
