They cover If The Kids Are United, and they have a song called tattoo and another one called welcome to meth city. What album are these songs from?
I looked it up, and it said tattoo wasn't on an album, was it on an E.P? try google.
Tattoo is on Give "'Em The Boot V" its a horrible rancid song btw. i think it might be one of there new songs.

If the Kids are united is on the cd "Give 'Em The Boot II" and matt freeman rips it up with his bass riff its a really good cover

sorry havnt heard of meth city
