Wow, I wonder if he lost his shrink-wrapped original copy of
Smiley Smile, which as of 1979 he kept in the garage (according to, IIRC, an interview he and Carl did with Time Barrier Express that year)!
Granted, this would be several garages later. Granted, Bruce is barely on that album (just "Good Vibrations", and maybe the tag of "Vegetables"). Granted, "Stuff" doesn't matter, as he says here.
