Ned (thanks Ned!) informs me of this post made by Gail on the Zappa.com forums:
Re Little MOFO – We are informed that the release date is officially 5 December and you could easily see it in the stores that week in the U.S. As for the Mother of Freaking Out, we think it could start shipping as early as the following week but there will be an Official Update at Zappa.com sometime this week when we confirm real information. Just so you know, we did just get a little MOFO in our hot little hands but not the MAMA. One more thing – the baby MOFO is not a prequel or a sequel (should it come out either before or after MOFO Deluxe) – it is of course geneticaly related but was brought into the world with its own material as well. We did not want to leave anyone out over a budgetary concern. We deemed it a necessity to make this an all inclusive release option, given that FZ’s Music (et al) is the world’s finest optional entertainment.
