RobMac says regarding Van Morrison, " I always liked him but was not real familiar with his music until I started collecting bootlegs about 25 years ago."

We're in a strange place in the history of rock music:  more music is available than ever before, but the rock and roll audience is beginning to die off.   The archival material from the 1960s is four decades old....if they don't release these shows now, then when?  At some point it passes out of copyright and it's going to get released by some fly-by-night company pressing up quasi-bootlegs in some hard to litigate backwater like Belarus, so why not figure out ways to get some of these archives in front of the public while there's still a paying audience alive?

I know that there were once issues involving crowding up an artists' back catalog with live recordings or inferior outtakes, but jeez, you can follow the lead of the Grateful Dead and release 'em as mail order or Internet-only sales.  Or put 'em out as bonus discs.  Morrison's just remastered a huge chunk of his back catalog; why not make some of these live broadcasts available as bonus discs?  

I'm glad that Wolfgang's Vault has done us the service of making this material available.   I'd be willing to buy some of these as hard-copy cds, too.  I guess the issue would be whether or not there is enough of an audience to warrant pressing up copies.   The obscurities (Poisette-Dart, anyone?) probably couldn't support hard-copy archival CD releases out in Meatworld, but the big names (Springsteen, Morrison, Stevie Ray Vaughan, etc.) certainly could.
