When I heard that these new editions of 60 of Frank Zappa's classic albums were coming out, I was both overjoyed and puzzled, but also curious enough to see whether there would be any sonic upgrades from what was out there before from Rykodisc and other sources.  The mastering for this album is fantastic, except that this edition omits the extended "Didja Git Any On Ya"; I wonder why.  Also, I want to note to others who really like the jam called "Orange County Lumber Truck" that, if you really like that bit of instrumentation by this particular group of Mothers, seek out a copy of a disk called MOTHERS AHEAD OF THEIR TIME which contains the full jam; it cooks!  Hopefully, some of these missing pieces will end up on their own compilation or we will indeed see a reissue of the afore-mentioned MOTHERS AHEAD OF THEIR TIME disk!
