I remember buying this as a 7 inch live ep with gatefold sleeve in 1981, funny thing is, this was the only track i listened to, cant for the life of me remember what the other songs were, but they were all live recordings,
It is not rare, it is on a couple of compilations, one is called Vintage Magnum. Still great though. And... I was in the audience at the Marquee when this was recorded and saw them on the tour in March '80 at UMIST in Manchester.
