We tried to rope our old pal Andrew W.K. into doing the original Undercover series, but our schedules didn't quite mesh. We're making up for that with two Holiday Undercover appearances--the second, which features a very special guest, will air tomorrow. Here, you'll see Andrew deliver a beautiful, harrowing solo rendition of "Silent Night," a classic that dates back to about 1816: Andrew tells us it's one of his favorite songs of all time. What else has Mr. W.K. been up to lately? Oh man, you can see him on the Cartoon Network show Destroy Build Destroy, as well as on tour. His sorta-lost definite-classic Close Calls With Brick Walls was recently issued in America, packed together with the rarities compilation Mother Of Mankind. Add it to your wish list, and tune in tomorrow for Andrew, Part 2!
