"He was so prolific. He used to make me laugh because whilst I was working on an album, he would have done two world tours, a couple of albums (and) a film. He was really playful and really sweet. What a talented man, what an artist. I think it’s a terrible loss that he should go at such a young age, its incredibly sad." Kate Bush remembers her friend Prince, who died in April (16). The pair worked together on the song Why Should I Love You from Bush's 1993 album The Red Shoes.
