311 had a different guitarist way back in the late 80s named Jim Watson. He went skinny dipping at their local YMCA and was taken back home to his parents still naked. Police Code 311: Indecent Exposure.

He was replaced with the amazing Tim Mahoney (who just celebrated a birthday yesterday), and they've held that line up ever since Jim left, also in the late 80s.

Well, SA joined a little later than Tim, but then I guess you could say that when SA joined, the real 311 started. There are many early tracks recorded before SA joined, but I don't know that any of them are Jim Watson on guitar.
