[b ] i think ALS is the best son the band ever wrote and i think it's easily one of the top 10 songs of all time.led zep's performance at knebworth was the best live performance live by a rock band ever.listen to the guitar,vocals,booming bass lines,and bonzos shotgun blasts on the drums if you think i'm wrong.if i were any a band,everytime i played a song i would stretch myself to try and play 1/4 the level they played that song at.it's just a thing of beauty plain and simple!!!
