The original track name is 'Nudge & Shouter - Blue Lagoon', released as the first release of 'Push Up Records'.. after the big success of the first pressing 'Tunnel Records' renamed the track and re-released it under 'Tunnel Allstars'.
also there was a problem around the 'Mellow Trax Remix', because the label only paid for a 'Dj Mellow-D Remix', but they have put 'Mellow Trax' on the release (Mellow Trax was super popular in 1999 and a remix under the name was much more expensive)..
here is the legendary original mix:
