enchantgy:

It has been heavily remixed (butchered) for the release of Tribute. The guitarsolo you hear on the vault recording is actually NOT on the Tribute album though.  (the Tribute solo was recorded in Montreal)

The above is incorrect.  The Vault show is the unreleased concert recorded by King Biscuit (remember, Bill Graham's archives and King Biscuit's archives merged).  It is absolutely not the premix of Ozzy's Tribute album. 

The Vault show is an unbelieveable recording that a lot of people, myself included, prefer over the Tribute album recording, as there are even more great guitar fills on this show.  Randy really let loose.  To quote Quiet Riot's Kevin DuBrow, "My favorite playing of Randy's with Ozzy is on the live King Biscuit radio show".  One of Ozzy's former guitarists, Joe Holmes said "I got the King Biscuit Flower Hour tape from '81, and he played great on it.  I'm picking off a lot of fill-in riffs from that." 

I've listened to this show over 300 times and never tire of it.  Hopefully this will be available on CD soon along with other Vault shows cause I'll be the first in line to buy it no matter the cost, as long as there's no compression, like mp3's or streams have.

The original KBFH promo and cue sheets for this show erroneously list Bob Daisley and Lee Kerslake (along with misspelling Randy Rhoads' last name) when Rudy Sarzo and Tommy Aldridge played bass and drums respectively.  That is probably why the notes on this show are as such.

Many thanks to Wolfgang's Vault!
