Desmond has a barrow in the marketplace
Molly is the singer in a band
Desmond say to Molly, girl I’d like to punch your face
And Molly says this as she takes him by the hand

The story:

I said to a friend that I would want to punch her face too if she kept spouting gibberish like that. They wondered what I was talking about and guffawed with laughter when I explained about the bit where Desmond wants to punch her face.
