Some exceptions remain, and so the stereo mix of "Pet Sounds" does contain some differences from the original mono mix. Among them, alternate vocal parts used for the bridge of "Wouldn't It Be Nice" and the end of "God Only Knows" due to the original tracks no longer existing. "You Still Believe in Me" features a single tracked vocal instead of the doubled vocal of the original due to a missing tape. In the mono version, chatter can be heard buried in various tracks; instances of them were omitted from the stereo version at Brian's request.
