Feature pitch

I sent my editor a pitch on folk-singing, with the line: 'Fancy a feature?'

He sent me this:

I met a tart the other night and she said, "Pleased to meet ya."
So I looked and said with a jerk of my head, "Well, how's about a feature?"
I grew more bold
As we drank ice cold.
She got a packet of fags out.
I said: "More beer?"
She said: "No thanks dear.
"Tonight I've got the flags out."

It's by Barry Humphries, I'm told.
