A couple years ago, I learned the bass part to "Good Vibrations." I haven't verified it recently, so this is it as I remember. I'd thought I knew the organ part during the beginning, but it sounded weird, so I didn't include that.
I'm pretty sure the organ part I do have is right, although the C major on the original sounds lower, so it's probably an inversion. I'm not a very good harmonica player, but I did the harmonica part too.
