As the whole point of the jingle is to make you remember both them and more importantly the product, I was wondering how many of them we still do remember and if they do make us buy the product.

In some cases I think they work so well, we often remember the jingle long after the product has ceased to exist. I wonder if there are many examples of this and also I wonder the reason why?

This still exists, well I know it does as Mrs Shanbles has just shown me the bottle she picked up today. This jingle works so well I wonder why they ever changed it?

1001 cleans a big big carpet, for less than half-a-crown.......for less than half-a-crown.

Well one reason is that there are no more half-a-crowns....
