In October 1990, the KLF launched a series of singles with an upbeat pop-house sound they dubbed "Stadium House". Songs from "The White Room" soundtrack were re-recorded with rap and more vocals (by guests labelled "Additional Communicators"), a sample-heavy pop-rock production, and crowd noise samples. The "Stadium House" versions of "What Time Is Love?" and "3 a.m. Eternal" were immediate hits, with "3 a.m. Eternal" becoming the KLF's second, and the only one under the name, number-one release. These "Stadium House" tracks made up a large part of "The White Room" when it was eventually released in March 1991, substantially reworked from the original version. Aside from the singles, "Make It Rain", "Build a Fire", "Church of the KLF" and "The White Room" appeared in significantly more minimal, ambient and dub-oriented versions on the final album. "Go To Sleep" was reworked to become "Last Train To Trancentral".
