After the Houston video leaked, there seemed to be an indiscriminant feeding frenzy of begging for more new "leaks", most notably for audience concert videos.
Does a beggar really "need" an audience video clip, when so many different professionally video concerts are available?
Will a beggar really go hungry without Drammen, Yamaguchi, or every single 2005 concert audio bootleg, when many, many other similar high quality concert bootlegs are already available?
On the other hand, I considered both the Houston 77 audio and video to be "necessities" because they were professionally recorded and excellent sound quality.
At this point I would only possibly beg for alternate takes of old songs or for beg for "new" songs, and leave the rest of the serious collector's world alone.
