Also known as The Secret Psychedelic Mix. I picked this up last year. It was issued to promote the 20th anniversary re-issue of the parent album "Surrender". I remember liking this song back when it came out. At that time I didn't know who the guest singer was — Bernard Sumner — and if I had it wouldn't mean anything to me.
This is a pretty good mix. There's nothing "extra" in the mix, really, it's the same elements as the original 7 minute version, for 21 minutes this time, with perhaps some more production elements (more dubby stuff) but it doesn't seem to overstay its welcome.
