This song has a bit of everything to do with Classic Rock. Great vocals, great guitar work, and a back story that is more than the sum of its parts. This is a classic because it has it all. We have all heard it again and again, this is one of those songs that while we consider it a classic it will last on into the future of music.
This is a more modern video of the same song. Both are good I wish that there was a really good video that I liked more.
