The classic call-and-response between a questioner and a well-travelled cat who went to London to see the Queen, and spent the visit frightening a mouse. One of the most performed nursery rhymes there is, built for two voices trading lines.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
"Pussy-cat, pussy-cat,
Where have you been?"
"I've been to London
To look at the Queen."
"Pussy-cat, pussy-cat,
What did you there?"
"I frightened a little mouse
Under the chair."
