official or not http://rapidshare.com/files/101971829/Discotheque__Club_Remix__-_U2.mp3.html Please tell me
I don't think that this is U2. Must be some kind of cover/tribute, whatever... So, to answer your question: No, it's not an official U2 release.
These were the only Discotheque mixes that are officially in existence, if you're interested. Hope it answers your question - but maybe not. * Discothèque (12" Version) (5:08) * Discothèque (Album Version) (5:19) * Holy Joe (Garage Mix) (4:21) * Holy Joe (Guilty Mix) (5:08) * Discothèque (DM Deep Club Mix) (7:00) * Discothèque (Howie B Hairy B Mix) (7:39) * Discothèque (Hexidecimal Mix) (7:21) * Discothèque (DM TEC Radio Mix) (3:45) * Discothèque (DM Deep Instrumental Mix) (6:58) * Discothèque (DM Deep Extended Club Mix) (10:04) * Discothèque (David Holmes Mix) (6:14) * Discothèque (DM Deep Beats Mix) (3:59) * Discothèque (Radio Edit) (4:34) * Discothèque (Mexico City) (5:16) And the cover versions - I couldn't get the times for these. * Discotheque - Drag * Discotheque - Exit ^ * Discotheque - Intra-Venus * Discotheque - IRA ^^^ * Discotheque - Studio 99 ^^ ^ Exit is an unknown German male vocalist, not the well-known female tribute band. ^^ The Studio 99 version is really boring and not worth getting. ^^^ The IRA this mix refers to is not the IRA but the Irish Rock Association.
