You wanted history? They gave you history.
The majority of the guests came out during Eminem's 100-minute headlining set, which followed Jay-Z's phenomenal opening performance. Before long, the cameos were starting to get more consistant that lined Em's set: Drake joined him for "Forever," returning a favor for when Em appeared at the Toronto rapper's hometown performance earlier this summer; 50 Cent and Lloyd Banks came on for mini-set of 50 Cent songs, including "Patiently Waiting" and "In Da Club"; and Dr. Dre appeared wearing a Proof shirt, to honor late great detroit rapper Proof who was gunned down and killed in Detroit in 2006 and believe it or not he even did a small set of songs with Em, including "Nuthin' But a G Thang" and "Still D.R.E." Em got the crowd to chant for Dre's long-delayed "Detox" LP as Dre left the stage, and Dre's response was 2 simple words....  "I'm comin!"
