This version of Summer Days (And Summer Nights) called California Girls has inferior sound to two later versions of the CD; one released just this week that includes the album in BOTH stereo and mono songs. The other version is a two-fer that has The Beach Boys Today coupled with it. It is not clear whether the latter of these two will remain in the EMI/Capitol catalog now that the new release is available, but it is the BEST VALUE of the versions I have or have sampled. You will find it here: Today/Summer Days & Summer Nights (+B-Sides)
