One of the first LPs I ever bought... it was going cheap in the local record shop bargain bin and I liked the look of the sleeve art.
I've not heard it for a long time but the spoken between track dialogue you quote sounds vaguely familiar.
People here might frown if I suggest this LP can be easily googled for music nostalgia blogs hosting the full album mp3 download, to confirm if it's the one you are looking for.
