Apple Music: I don't have itunes so I don't have a link yet, sorry.

But the BEST place to listen to it (and cheapest place to buy it) is on Bandcamp, where you can get an uncompressed download if that's your thing:
I'll sort that apple link out in due course.
I would say, "Enjoy" but it's not really that kind of song...
