Look for Zakk Wylde to share a TV studio stage with The Roots tonight.  The Black Label Society founder has a date with the house band on "Late Night With Jimmy Fallon" on this evening's episode on NBC.  Wylde now joins a list of rockers -- including Slash and Bruce Springsteen -- to sit in with The Roots.  Last month, Wylde's Black Label Society was back with another album.  The band's "unplugged" acoustic project, "The Song Remains Not The Same," features reworked versions of BLS tracks from throughout the group's career.  Wylde named the record in honor of Led Zeppelin's concert film "The Song Remains The Same."
