Livin' on the Fault Line is the seventh studio album by the American rock band the Doobie Brothers. The album was released on August 19, 1977, by Warner Bros. Records. It is one of the few Doobie Brothers albums of the 1970s which did not produce a Top 40 hit on the Billboard Hot 100. Tom Johnston left the band early in the sessions. He is listed as part of the band but appears on little or none of the actual album. He wrote and sang five songs during the sessions for the album, but subsequently quit the band and withdrew his permission for the Doobie Brothers to use these songs. The track "Little Darling " is a remake of the Marvin Gaye 1966 hit.
