Basically here are the changes When Joe s Garage Act I was released on CD in 1987 the same year the Box Set edition was released on vinyl it put in the same package as Joe s Garage Acts II III The track Wet T Shirt Nite was changed to Fembot in a Wet T Shirt Toad O Line was changed to On The Bus and the Central Scrutinizer s dialogue from the end of Lucille has Messed My Mind Up was separated into its own track entitled Scrutinizer Postlude I don t know about the remastered vinyl box set that came out the same year but I assume it had the original names The only thing close to an explanation I ve ever heard for any of these changes is the Fembot in a Wet T Shirt change I ve looked it up and as far as I can tell it was the subject of a discussion that took place in Frank Zappa s Society Pages fanzine issue 3 which was published in 1991 Rob Samler What is a Fembot in a wet t shirt Frank Zappa Do you remember the Six Million Dollar Man Rob Samler Uh huh sure Frank Zappa there was an episode where they were being attacked by fembots these Female Robots if she enters a wet T shirt contest what happens Den Simms Sparks fly Rob Samler So why did you change the title on the CD Frank Zappa Why what does it say on the CD And that s all I don t actually have the magazine but I ve heard about the discussion from here and this has information about the publication and here s an eBay listing for the issue So that s basically all I know
