Does anyone know who wrote/sang the following:

Someone I know is treating you bad,
Someone who ought to know better than that.
I thought I knew him well,
But you can never tell,
We don't get on so well, any more.

Someone I know is making you cry,
Someone who should have been eager to try.
But he grew worldly wise,
And he new how to lie,
We don't see eye to eye, any more.

Someone I know is waving goodbye,
Someone who should have been happy to be
With someone like you,
But it couldn't be true,
Someone I knew, someone called me.

It was on Folk on Two over ten years ago...?

Be greatful if you could help.
