I thought this was awesome. You can't help but to get a little emotional while watching Robert Plant and Jimmy Page.
When I was in high school there was a theater down on Colordo Blvd in Pasadena where every weekend they would have a midnight showing of The Song Remains the Same and Rocky Horror. If I had to guess I would say I saw the song remains the same at least 25-30 times and seen their last tour before John Bonham died.
