What is nice about 12 inch is that they’re usually 45rpm, which has a better sound. What is less nice about them is that they usually come with longer versions of the same song. For prog rock this is usually a good thing, and meant that way. For this one it is not. After the radio edit comes the repetition.
Picture discs were collector items back in those days. This is one of them, and a particular beautiful one at that. It comes with a total of four songs, so it might also be called an EP. And there is something very special about having the portrait of Terence spin around at 45 rpm on your record player.
