This CD single is about as rare as you can get - it's never been released! I got this copy around the end of January 1999, and at the time of writing (mid-November '99), it has still not been released.
Click on the front cover to get a picture of the back - it's twice the size of the front and is 111k large. The back is full of praise from the British press for Sarah's album Surfacing, which was released in the UK on 21st September, 1998.
