Symptom of the Universe - Black Sabbath (but Ozzy's live version on Speak of the Devil). What is odd about it is that the band members (Rudy Sarzo, Tommy Aldridge, and Randy Rhoads) refused to do the live album of the Black Sabbath covers. They felt they where too accomplished musicians to do Sabbath covers. It eventually lead to the firing of Rhoads, but he agreed to perform on the album to fulfill his contract agreement. Ozzy several hours before he drunkenly pissed on the Alamo and was arrested, fired the whole band. He said he didn't remember doing it. This all happened right before Rhoads died in a plane crash. Brad Gillis would become the guitarist for the live show / recordings.
It is one of my favorite albums, loved the live sound. Rudy Sarzo is one of my favorite bassist. Jake E Lee still today is my favorite guitarist.
