I thought it was King's Lynn, but if there are other Lynns about, why not them?
Always liked the bag-pudding rhyme, too, especially the picture of the queen in crown and robes, wielding a very large frying pan.
Which reminds me of another rhyme:

In days of old when knights were bold
And pants were made of tin,
No mortal cry escaped a guy
Who sat upon a pin.

Profound thought, that.
(tee hee!)
