Doug "Cosmo" Clifford (born April 24, 1945 in Palo Alto, California, U.S.) played drums in the American rock band, Creedence Clearwater Revival. After CCR broke up, Clifford and former CCR bassist Stu Cook (who was born a full day after Cosmo Clifford) joined Don Harrison in the Don Harrison Band and also issued a solo album.

In 1995, Clifford and Cook formed the band Creedence Clearwater Revisited. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
