This past Sunday, during a performance at the Warfield in San Francisco, former Operation Ivy frontman Jesse Michaels joined his previous bandmates Tim Armstrong and Matt Freeman, during Rancid's set to perform "Unity". Rancid has been performing the song, along with others from the Operation Ivy catalog, on a recent tour, but this is the first time Michaels has joined in.
