This video is totally worth watching. The first few minutes are clips of Cole performing on stage, but the last few minutes has a drunken Cole and friends doing Michael Jackson karaoke and he's even joined by Wale. The two would collaborate on several tracks, most memorably "Beautiful Bliss" where Cole spit one of his best verses ever.
There's a video of J. Cole and Wale on YouTube drunkingly performing Michael Jackson's "P.Y.T." at a karaoke bar in Norfolk, VA.
