What do you have going on tomorrow night? Whatever it is, cancel it. No, really. Call up your friend or your girl or your coworker who just asked you to grab a couple brews tomorrow night and tell 'em you're busy. Because the Lenny Cooke documentary, Lenny Cooke, will be airing on Showtime for the first time on Friday night. And if you haven't seen it yet, it's must-see TV.

If you're not familiar with Cooke, we did an interview with him back in early December when the documentary was released in theaters. You can read it over here. And if you're interested in checking out the documentary, it's set to air tomorrow night at 8:30 p.m. EST tomorrow. Watch it or set your DVRs accordingly.
