Geoff and Babs Boughton used to sing one about still loving (etc.!) in old age. Great song and I would love to learn it but can't find it anywhere. Can anyone help?

At the grand old age of 52 I feel it is getting more and more appropriate.

The only words I can remember from it is:

"As long as you're able to wind up me clock
there's no need for to worry."
