The Beach Boys Wild Honey(Sunshine Tomorrow) 2CD Set?

Why didn't the liner notes identify the live "Aren't You Glad" as coming from the Big Sur concert 10/3/1970?  It is clearly from that performance - check out youtube Big Sur Beach Boys or the Goodbye Surfing Hello God boot set.  Could it be BRI doesn't have the rights to the Big Sur concert and so they circumvented that by not identifying the venue and date?  Kind of like how Alan Douglas didn't identify the tracks from Royal Albert Hall that he used on Hendrix in the West?

Also does anyone else think the sound quality of Aren't You Glad is better on Goodbye Surfing Hello God than on Sushine Tomorrow?  I wonder if they deliberately degraded the quality with EQ and compression to make the sound fit in better with the less well recorded Thanksgiving tour recordings.
