Johnston quit the group in 1975, and was replaced by Michael McDonald, whose interest in soul music changed the band's sound until it broke up in 1982 . The Doobie Brothers reformed in 1987 with Johnston back in the fold and are still active, with occasional contributions from McDonald . Every incarnation of the group emphasized vocal harmonies . The Doobie Brothers were inducted into the Vocal Group Hall of Fame in 2004 . </P> <P> Drummer John Hartman arrived in California determined to meet Skip Spence of Moby Grape and join an aborted Grape reunion . Spence introduced Hartman to singer, guitarist, and songwriter Tom Johnston and the two proceeded to form the nucleus of what would become the Doobie Brothers . Johnston and Hartman called their fledgling group "Pud" and experimented with lineups (occasionally including Spence) and styles as they performed in and around San Jose . They were mostly a power trio (along with bassist Greg Murphy) but briefly worked with a horn section . </P>
