Drummer John Hartman arrived in California in 1969 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.
In 1977/1978, the lineup for The Doobie Brothers featured current and founding member Pat Simmons as well as famed keyboardist Michael McDonald , drummers/percussionists John Hartman and Keith Knudsen , iconic guitarist Jeff “Skunk” Baxter , bassist Tiran Porter and vocalist Bobby LaKind . Simmons currently tours under The Doobie Brothers moniker with a band that includes longtime members Tom Johnston and John McFee.Tags: The, Doobie, Brothers, The, Doctor,
