Let us know how you feel about mono versus stereo Pet Sounds, ay? I have a half-dozen copies of the album (LP and CD), but all mono, out of deference to Brian (he's almost deaf in one ear, and always mixed to mono). By the way, all the early BB albums (up to and including Wild Honey) were mixed to mono only, the "stereo" version offered by Capitol Records actually being "Duosonic" (Capitol's reprocessed mono to pseudo-stereo) EXCEPT for Surfer Girl, which is true stereo, for some reason.
