I heard the song yesterday (and liked it a lot) and wasn’t familiar with Hillbilly Moon Explosion. The male voice was familiar and I couldn’t place where I had heard him before until I found the video and realized it is the lead singer from Demented Are Go, which the last time I think I heard anything from was “Pervy in the Park” in 1987/88.
Damn I am getting old, his voice got better over the decades (I like the gravely type voices, male or female). I guess old school Punk doesn’t really go away (well hillbilly punk at least).
