I love the Doors. Can't really pick just one song as my fave though. I could say "The End", but that's typical, and somewhat parallel to saying "Stairway" is my fave Zep song. I have a huge plaque of Jim Morrison on my wall.
I used to say that had I been of concert age in the late 60's/early 70's, the Doors would've been my band. But that was of course, before I discovered Zep.
