The following lists detail most of these, but are not exhaustive. Pure Trance 1 "What Time Is Love? (Pure Trance Original)" (catalogue number KLF 004T) was first released on 17 October 1988, and deleted following initially low UK media interest and sales. The reaction from continental Europe's clubbers and DJs led to further European releases in 1989 and 1990. In late 1989, a US edition of "Pure Trance 1" (sea-green writing on a black sleeve, and slightly different typography) was issued on the TVT label, including a live version taken from The "What Time is Love?" Story. The KLF's "Pure Trance" series was originally envisaged as comprising five "Original" 12" singles and five "Remix" 12"s. The "Pure Trance Remix" single of "What Time Is Love?" was released on 24 July 1989. KLF 004T was re-released in the UK on 15 July 1991, during the peak of the KLF's chart success, along with both "Pure Trance" mixes of 3 a.m. Eternal. Key Live at Trancentral "What Time Is Love? (Live from Trancentral)" was released on 30 July 1990, and the single of remixes "(Remodelled & Remixed)" followed on 20 August 1990. The main B-side accompaniment of "What Time Is Love? (Live at Trancentral)" was the "Techno Gate Mix" of the track, which retained the title track's rhythm and bass as a backdrop to extensive samples of Jimi Hendrix's "Voodoo Child (Slight Return)". Another UK 12" featured instead the "Wandaful Mix", which sampled from Wanda Dee's "To the Bone". Key America: What Time Is Love?
