Query: Great Live B-sides

Obviously, you've heard the song 'Light Years,' so there's no sense in talking about that...but the live version of 'Grievance' makes this single more than worth it...more energy and punch than the album's version, this song really flies live. And the timid little version of 'Soon Forget' is quite charming in itself. Another great Pearl Jam single...
