Producer William Orbit, who worked on the Jackson track, says: "When I first played it in my studio I opened a trove of delights. Hearing Michael Jackson's vocals was stirring - so vivid, so cool, and poignant; it was like he was in the studio singing live. With Freddie's vocal solo on the mixing desk, my appreciation for his gift was taken to an even higher level."
