Who do you think are the best classic rock bands?

The Beatles - single - handedly changed the face of music. Not just rock music, but music in general. Each member was larger than life and as a collective unit there probably isn't a single rock band that has influenced a larger number of listeners. They are often attributed as inventing rock music and paving the way for that was to come.The Beatles, while around for only a relatively short period, came out with an incredible amount of music, all of which was of legendary caliber.
The Doors - Jim Morrison, without a question, was the first through and through "rockstar." He wrote the book on rock debauchery and has since become iconic not only because of the Doors, but because of his larger than life persona. The Doors trangressed time and space with their ethereal mix of poetry, rock, jazz, and r&b.
Queen - in my opinion, there has not ever been aa better band than Queen. You have four guys that all wrote endless number one hits. What i mean is each individual member is accredited numerous number one hits as sole songwriters. Each member had a distinct style and as a team were one of the very best live shows, still many of which hold records for attendance and grandeur.
