"Oranges and lemons", say the bells of St. Clement's

You probably know this nursery rhyme.

It has more verses than are usually heard in the playground, and one of JoJo's favourite books has them all. I can make

Pancakes and fritters
Say the bells of St. Peter's

rhyme by pronouncing the name of the church as 'Pit-ers'.

But

Maids in white aprons
Say the bells at St Catherine's

??? I don't think so. Anyone?
