Two thoughts:-
Song remembered from child-hood,
Give me a piece od Roly-poly,
Roly-poly pud,
Whether it's treacle or jam,
It's lovely, tell your Mam!

Wartime cartoon:-
Two large soldiers and one small one sat at a table , on which sits a Roly-poly pudding. One of the large soldiers is cutting it in half, whilst the other one explains to the little guy 'Me and Bill likes ends!'
