Great quiz! I only missed Dirnt, Inez, Kinney, and Mendel. P.S. you may want to accept some alternates when multiple people filled the same position. For example, Pearl Jam had multiple drummers in the 90s. I tried Jack Irons.
Nice, I see you added the PJ drummers. Other possibilities: Dave Navarro was lead guitarist of the Chili Peppers in the mid-90s. Pat Smear was rhythm guitarist for the Foo Fighters until '97 (rejoining again in 2010).
I don't think Navarro is worth adding. He was only there for one mid album. Smear would probably be a good add as would Mike Starr for AIC. I think I'll do that. Thanks for all the advice!
