abandoned the musical direction of the soundtrack and single. Meanwhile, "What Time Is Love?" was generating acclaim within the underground clubs of continental Europe; according to KLF Communications, "The KLF were being feted by all the 'right' DJs". This prompted Drummond and Cauty to pursue the acid house tone of their Pure Trance series. A further Pure Trance release, "Last Train to Trancentral", followed. By this time, Cauty had co-founded the Orb as an ambient side-project with Alex Paterson. Cauty's ambient album Space and the KLF's "ambient house" LP Chill Out ambient video Waiting were released in 1990, as was a dance track, "It's Grim Up North", under the JAMs' moniker. Throughout 1990, the KLF launched a series of singles with an upbeat pop-house sound which 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 first "stadium house" single, "What Time Is Love? (Live from Trancentral)", released in October 1990, reached #5 on the UK Singles Chart and hit the top-ten internationally. The follow-up, "3 a.m. Eternal (Live at the S.S.L.)", was an international top-five hit in January 1991, reaching #1 in the UK and #5 on the US Billboard Hot 100. The album The White Room followed in March 1991, reaching #3 in the UK. A substantial reworking of the aborted soundtrack, the album featured a segued series of "stadium house" songs followed by downtempo tracks.The KLF's chart success continued with the single "Last Train to Trancentral" hitting number two in the UK, and number three on the Eurochart Hot 100. In December 1991, a re-working of a song from 1987, "Justified & Ancient" was released, featuring Tammy Wynette. It was another international hit – peaking at number two in the UK, and number 11 on the Billboard Hot 100 – as was "America: What Time Is Love?", a hard, guitar-laden reworking of "What Time Is Love?". In 1990 and 1991, the KLF also remixed tracks by Depeche Mode ("Policy of Truth"), the Moody Boys ("What Is Dub?"), and Pet Shop Boys ("So Hard" from the Behaviour album, and "It Must Be Obvious"). Neil Tennant described the process: "When they did the remix of 'So Hard', they didn't do a remix at all, they re-wrote the record ... I had to go and sing the vocals again,
