what a fun tune!
it's a real basic arrangement that works.
great performances that shine thru when i can hear them......
i have some mix issues, background vox are too light, lead vox is too hot, and the bass guitar needs some 'clarifyin' of some sort....
it's a little muddy, but not woofy......
a lot of the fiddle licks are just lost...
my guess is, you'd have to do fader rides between when you want the lead and backup vox to be more upfront, and bring those down when you want the fiddle riffs to stand out..
or, panning just during those sections might help....
but whatever it is to dial in the mix, the song and performances are there.
nice job.
