From last.fm:

The Murder Junkies are a GG Allin tribute band, most known for being the actual backing band of deceased punk rock performer GG Allin. They are the third GG Allin backing band to bear the name. The original Murder Junkies was a Texas band - formed independently of Allin - which performed as his backing band for several live dates in the late 1980s.
