Johnny Hobo and the Freight Trains consisted of songwriter Pat the Bunny on guitar and vocals, Jeff-Face on harmonica and vocals, Flash-C on trumpet, Ian Skumfuk on washtub bass and vocals, Roman on bicycle and vocals, and Rockstar Mike on washboard, bass drum, and vocals. Often at shows, it would just be Pat and his acoustic guitar and sometimes harmonica; other musicians would often join from outside the usual lineup. Alcohol, drug use, politics, and the punk scene were common themes in Johnny Hobo songs.
