Very entertaining.
Creative lyrics and Rob did a good job with the fiddle.
I like the liberal use of tremolo to give it that slightly sinister feel.
There are a couple of things I might suggest, perhaps a few more variations of Robs part on some of the repeats or maybe even a full blown solo.
Maybe a section where the bass moves up a gear to a more rhythmic, faster paced, maybe walking bass line.
A finally maybe just back off your mates ‘aahh’s’ a little, which slightly drown out the main vocal.
All in all though, I enjoyed this muchly.
