One that my husband learnt from his father, who came from Stirling is:

One and one is two, Two and two is four, Four and two is six and six is twelve. Twelve and twelve are twenty-four, Add sixteen and you get two score, A seven and a three make it half a century, And if we have not blundered, Add forty-four and five, And as sure as you're alive, You only need one more to make a hundred!

If anyone knows any more about this song, we'd be delighted to hear.

All the best, Barbara
