The Doobie Brothers
John Hartman (born March 18, 1950) is an American drummer who was a co-founder and original drummer of the Doobie Brothers. At the band's inception, Hartman was the sole drummer. However, in late 1971, the group added second drummer Michael Hossack, and the dual-drummers formation has persisted ever since. (Hossack was replaced in 1973 by Keith Knudsen.)
