Ok, I'm tapping into some old brain cells here so don't quote me word for word here:
After Cliffs death(RIP)they auditioned a "few" prospects(maybe 1000 applied)& even Les Claypool auditioned for them because he just wanted to jam with them(imagine)& hopefully land the part BUT was rejected because he was TOO good & didn't fit their criteria(oh well). I LOVE Claypool's version of "The Thing That Should Not Be", killer stuff without totally ruining it, IMO.
Then, after auditioning a few likely people, they settled on Newsted, who had just finished his first & only recording/semi-tour with Flotsam(Doomsday For The Deceiver/Metalblade/'86)that I happen to like in some parts(especially "Fade to Black", LOL, hmmm, what band do I REALLY want to be in)ONLY accepting him because Armored Saints bassist Joe ???(forget his name now)was Metallica's first choice as a replacement but he did NOT want to leave his band for them!(again, imagine)So they took in Newsted because they needed a good solid bassist that knew ALL their material(Jason was a Met. buff & fanatic)+ they were in the middle of their tour upon Cliffs death & were getting flack from the label & promoters about cancellations(ahh, good ol' rock & roll politics)so they brain washed him & basically controlled him throughout his term(shame, because he can play, just not MY bag). They also settled for him because he was totally different than Cliff & they didn't try/want to "fill his shoes" with a wannabe replica of him out of respect & knowing it would be IMPOSSIBLE...
The End,

PS: I've seen Rob T & he is an amazing player in chops & flash. Should've stayed with Ozzy
