I loved this analysis! This made me go and listen to the Geeshie Wiley version and I think you’re right on the money.

The one thing I might add is that I think the vampirism might be a metaphor for the pressure to assimilate into a colonial culture, which is how you get that super corny, appropriative version of “Picked Poor Robin” vs the rapturous “Rocky Road to Dublin Town” despite them both being sung by Remmick.

If I’m remembering the movie correctly, the recently turned vampires are not themselves exactly, they share a hive mind (which could be another allusion to the pressure of assimilation/ mono culture) but they also seem to still retain something of themselves, even if it’s only partial because of the force of the vampirism.

So I think the version of Remmick that’s performing the cheesy “Robin” tune is a representation of the part of him that took a deal with the devil that allowed him to gain the “privileges” granted by vampirism/whiteness.

But while he can “pass” as an assimilated white man (with his fake North Carolina accent) there’s still the part of him that has not fully let go of his culture/humanity—and that’s where you get “Dublin Town.” I think it’s also significant that the song has a complex meter structure (it’s either mixed meter or 5/4—I’ve struggled to count it) which is a nice counterpart to Delta Slim talking about how white folks struggled to keep a beat and he would change the timing of the songs to confuse them more.
