Yep, Jan would do it over and over again until he either got it where he wanted it, or would slap it on as album filler and come back to finish it later. That's what happened with DMC; Jan wanted to keep working on it, but he needed to submit a completed album so he put the earlier version on the Drag City lp and then kept working on it for a single release. NGIS has a more convoluted history but there are three completed versions. There are two versions of (HTC)FAOTW and two versions of YRKHTHAG. I know Jan worked on Popsicle and Hot Stocker again around '65. Dean, PF Sloan & Artie Kornfeld have all said something to the effect that the technological limitations they faced in mixing AAACSCBRATA down for radio airplay diminished that record, so Jan also faced limitations but I think he had to balance these things more. Trying to work with everything that went into his musical career while pursuing a medical degree meant he sometimes had to round out albums or submit singles that weren't everything they could be, and letting matters that weren't going to yield sufficient results (like remixing AAACSCBRATA) go if he was going to achieve what he knew needed to happen.
