Who is the greatest classic rock band and/or guitar player?

Led Zeppelin, hands down.

Honorable mentions go to The Stones, the Beatles (are they classic rock?), and the Allman Bros.

DC

DEEP PUPRLE MK2

while i realy like led zeppelin i think that Deep Purple and the after deep purple bands with people from the band like rainbow realy changed rock music.

man this is a BROAD topic...

are black sabbath rock? or were they the first heavy metal band? does it really matter?

I'd say Led Zep, Sabbath, AC/DC, Deep Purple, The Who, Rolling stones, band of gypsies, free, Camel

the list is endless, these guys and bands are all considered 'classic' for a reason.......

I would say Lynyrd Skynyrd man. They are the greatest band on Earth. And other bands like AC/DC, Led Zeppelin, and the list goes on.

Rock ON

I am personally think Guns N Roses. Led Zep come a close second with Pages masterful guitar playing/riffs , but for pure attitude and style, for me its guns. Watching Axl, Slash n co. rattle off classics like Nighttrain, It's so easy, Jungle... (the list goes on) is just amazing!
