This was Kate’s first CD single ever. Since it only got a promo release in the U.S. back in 1986, and never a commercial one, it quickly became a huge collectable and tends to be pretty difficult to come by these days. If you’re looking for this one and happen to come across it, you can probably expect to pay a nice bit of money for it.
It comes in a simple cardboard sleeve, and the artwork on the front and back is pretty identical to the UK 7” artwork. The biggest drawback to card sleeves is that the edges tend to wear out fairly quickly if they aren't properly protected.
This is a nice one to have in your collection. Since this one tends to be on the rarer side, it's also doubtful that you will find this for a cheap price.
