Basically here are the changes When Joes Garage Act I was released on CD in  the same year the Box Set edition was released on vinyl it put in the same package as Joes Garage Acts II  III The track Wet TShirt Nite was changed to Fembot in a Wet TShirt ToadO Line was changed to On The Bus and the Central Scrutinizers dialogue from the end of Lucille has Messed My Mind Up was separated into its own track entitled Scrutinizer Postlude I dont 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 Ive ever heard for any of these changes is the Fembot in a Wet TShirt change Ive looked it up and as far as I can tell it was the subject of a discussion that took place in Frank Zappas Society Pages fanzine issue  which was published in   Rob Samler What is a Fembot in a wet tshirt Frank Zappa Do you remember the Six Million Dollar Man Rob Samler Uhhuh sure Frank Zappa there was an episode where they were being attacked by fembotsthese Female Robotsif she enters a wet Tshirt 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 thats all I dont actually have the magazine but Ive heard about the discussion from here and this has information about the publication and heres an eBay listing for the issue So thats basically all I know
