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 (although "You Belong to Me" was a hit as recorded by co-author Carly Simon). Still, the album received modest critical acclaim. Tom Johnston (guitar, vocals) left the band early in the sessions. He is listed as part of the band (appearing in the inside group photo) but appears on little or none of the actual album: he wrote and sang five songs during the sessions for the album, but they were not included on the final release. The track "Little Darling (I Need You)" is a remake of the Marvin Gaye 1966 hit.
