It is kind of bittersweet in watching it.  For one thing, seeing these musicians at such a young age, but for another, all of their damn cigarette smoking, especially with Harrison dying in 2001 because of lung cancer.

And when it comes to their output, it amazes me what they accomplished from their first hit in '62 to their end in '70 and how what was seen back then with these men will probably be never seen again - by this I mean of their overall impact on music entertainment throughout the world. 

I wrote a long time ago with wonder what it must have been like to experience the Beatles phenomenon in real-time and the anticipation of a new album year to year and to experience their progression in those short 8 years.
