I didn't realize exactly how great Roy Orbison was until I saw his "Black & White Night" on PBS several months ago.  That session brought all of my memories together into one massive event.  I contributed to the PBS station just to get the VHS and CD versions of that concert, recognizing just how special it was.  I just now spent nearly five hours listening to that CD while I read most of the 115 reviews on Amazon (avg = 5 stars out of 5) of the DVD, and the advantages (editing, video enhancements, extra tracts) of the DVD over the VHS and CD version I have.  I just ordered two copies of the DVD (one to watch/listen to, and one for backup).
