Is there a reason that none of the recordings from the Fillmores, Winterland etc. are available for downloading?  What hooked me on listening to the 'Vault back in early March 06 was all the great music from my formative years in the 60's to early 70's, from Al Kooper to Frank Zappa (ok, my A to Z is a bit forced, what can I say....)  Some of those concerts are now available in the Concert Vault, but not one is for sale.  I would dearly love it if the Nice show from December 12, 1969 at the Fillmore West was available.  (At this point, I'd even settle for it just being in the Concert Vault.)
