Since 1996, Greg Hetson (Bad Religion, Circle Jerks), Eric Melvin (NOFX), and now Darrin Pfeiffer (Goldfinger) and Randy Bradbury (Pennywise), have organized a concept called Punk Rock Karaoke. The musicians listed will play a punk rock classic, with anyone and everyone open to grab the microphone.
The series has featured a number of familiar punk faces (The Descendents, Rise Against, Frank Turner, Fishbone, etc.), but it's also open to the general public right now. In other words: sign up and you may get to be in a video with the musicians above. Details here.
