Hi Paul! Firstly what a brilliant song and a brilliant band! It must have been a pleasure to mix their work.
Regarding your mix, I would tend to agree with jimi1969 about bringing the drums (though not the overheads) out a bit more. I would like to hear more punch on the kick and a bit more snap on the snare. Parallel compression could be a good way to go, but if that doesn't quite bring them out, something like Stillwell Audio's Transient Monster might find that lost energy. The banjo could also come up just a dB or two more, and the bass might also benefit from a hint of transient attack massaging. But my main comment would be that I love the mix apart from the huge amount of high end. I know my monitors are pretty bright, but playing this, it has the classic "mixer who spent 4 hours listening too loud" symptom of having too much top end sparkle. It probably sounds great on a small stereo, but might have hi-fi users reaching for the treble knob. Looking forward to hearing more of Rushford Mile
