Ah, yes, thank you Joy. But I am thinking more of the addition of the food to the toast *after* they have been cooked separately: what you describe would apply to, say, a welsh rarebit; but not to a fried egg on toast, where the frying would have to be done separately from the toasting. And the song specifies that the toast will be *buttered* BEFORE the addition of the [separately roasted] cuckoo, does it not? So there we must have some method in which the hands can be disengaged for the frying or roasting as the bread toasts, so that they can be timed to be ready at the same time — which surely bespeaks a purpose-designed grill or toaster mechanism.

I love eating too — which is why I regard this as so urgent a query.
