Rock City on Crackle with the Stones and many others who shaped that music

I have been watching the rockumentary Rock City on a website I have recently found called Crackle. It features the Rolling Stones and many other artists performing those great classic songs live in Great Britain. I am amazed and horrified by the knowledge of knowing what has become of some of them. Never the less it is shear beauty in its presentation and style. I really appreciate being able to look upon something that I probably only uderstand a little because it is either not mine to have or not my time yet or it is what it is.
