One of my favourite pieces ever and you haven't mangled it.
I played this live in a cover set a couple of years ago and had to make do with several VST Trons mixed. There are many covers Epitaph these days but this one is definately worthy of a listen. I also reccomend the BBC Radio John Peel show version which I believe is on the Epitaph compilation CD collection.
P.S. An EBow on an electric guitar makes a great emulation of the Tron brass on this track.
Best regards
Tee.
