Though he briefly mentions Rod Stewart, his main target was Michael Jackson. Davis and Jackson were extremely close; when Jackson was just in his twenties, he would often show up at Davis’s house unannounced to immerse himself in the archives, a room downstairs that contained videos of Davis’s performances over the years.
