I'm wondering how rare is rare.
A good observation Kelley. I have seen many dvd's with 'unseen footage', usually a snippet of a few seconds. That goes for books as well.
I've noticed an awful lot of Beatle magazine-type books at the grocery store check out lately. One claimed it contained never-before-seen photos and I was sort of tempted but resisted. Besides, someone had to have seen them...like the photographer and the editors.
