The album version. The single version is still 10/10, obviously, but the WHOOSH intro is lost WHICH, let's face it, is a call to arms on the dancefloor if EVER THERE WAS ONE.
Saint Etienne agree as well, when it was (about) #15 in their "All time best 100 singles we love" that they played at a Christmas party a few years back, they had the one break of the evening before it and I was told it was because they knew that WHOOSH would get everyone back on the floor straight away after the raffle!
