UK wise, I know only 'Ballad Of Youth' was released commercially as a single from 'SITT'. Then 'Hard Times..' & 'In It For Love' from Undiscovered Soul.

As for the rest of the world & promo wise, off the top of my head, there were also promo cd's for:

Stranger.. (also a US single?)
One Light Burning (Again, also a US single?)
Mr Bluesman, (I have a french promo cd of this one)
The Answer (Japanese single)
Made In America (Promo)
Undiscovered Soul (Promo)

And I seem to remember there being a Japanese promo cd for Rosie aswell.

I think that's all, could be wrong though.
