Orchard says: “Paul remembered that there were two unused lead vocal performances by Michael and himself. He said we should try putting the unused lead vocals onto the Jellybean mix. The Jellybean mix is a 12" and is much longer than the original version. It was originally made by making edit sections of the song with different instruments being muted to make up new sections and then spliced together.
“I needed to edit and arrange the alternative lead vocals to fit the 12" format. We then rearranged the vocal sequence and inverted the original performance so that Michael opened the first verse instead of Paul, to give the song a different take to the original version. Then we added additional backing vocal parts from the original multi-track to further enhance the instrumental mix. Paul then said it would be great to get Spike Stent to mix the new version of the track to give the song a new vibe.”
......So, from these remembrances; it appears as if there isn't any "new instrumentation", but some 'new' old vocals flown in.
I like the way it sounds. My views of it have changed over the twenty years.
