For Holiday Undercover, we did away with the master list of songs and simply asked bands to come to the ol' round room and play a song--with two rules: It had to be a cover, and it had to somehow be holiday related. Perfect timing brought us a return visit from The Walkmen, who if you'll remember were the last band to play in the original Undercover series. They came up with an excellent choice: Lindsey Buckingham's "Holiday Road," which you'll surely recall from its use in the movie Vacation. If you don't already have the latest Walkmen album, Lisbon, then you are crazy and you hate good music. Oh, and Holiday Undercover will run Tuesdays and Thursdays from now until the end of the month, except for one special week when it will run Tuesday, Wednesday, and Thursday. Happy holidays, and enjoy.
