Swinging her legs and puffing on a cigarette, she begins by whistling along to Pete's new tune - KP Nuts, a reference to their first names, Kate and Pete.

As he sings sweetly, "you're giving all your precious love to someone that I... I just couldn't find", Kate chips in with: "Rot in jail you c***!"

She then kicks out at him, nearly knocking him off his chair. Then, singing along with him, she jokes: "Sonny and Cher we're not."

The pair then have a bizarre exchange over one of his lyrics, when he sings: "Underneath the oak tree."

Kate then replies: "What oak tree?"

“The oak tree,�? says Pete.

To which she cries: “You're such a liar, such a liar. And a fantasist."

Pete then begins to sing the "la la la" section of the song, which prompts the woozy Kate to say "Don’t la la me".
