Neil Young, who seems to have become a focus here of late, takes over the music slot on "Late Night with Conan O'Brien" for the next four nights, starting tonight. Young follows in the footsteps of the Strokes, the White Stripes and U2, who all have held similar four-night stands on the show. Let's hope Young follows the example of the White Stripes, who used the slot to both plug a new disc by performing the single and to dip into the corners of the back catalog to unearth some cool music (in their case it was their fiery cover of "Jolene"). Young surely will play "The Painter" tonight, followed by other tracks from Prairie Wind. But one can't help but hope for an incendiary take of "Rockin' in the Free World" or "Powderfinger" later in the week.
