Regarding the SMiLE credits list above. There are two musicians who are missing from the list. One was considered a Wrecking Crew member that played bass on a lot of Beach Boys records and the other had a "woo-woo" machine named after him and played on Good Vibrations. Who knows who they are? I'm surprised the bass player was overlooked and I attribute it to an oversight, though maybe he wasn't around during the SMile Sessions (I doubt it).
I'm guessing you are talking about Ray Polhman and Paul Tanner lol.
