What is this tune called? Just SO brilliant.

New Order - Jetstream Lover (Tom Neville Remix)

It could be the Tom Neville Dub, but there's not much difference between them, and it's certainly one of the two. I prefer the Jaques Lu Cont Remix myself, but they're both good.

Has this tune been released? Can´t seem to find it anywhere?

Yeah, Juno have it listed as Jetstream, for some reason -
