Born in Palo Alto, California, on April 24, 1945 Doug 'Cosmo' Clifford's history runs parallel with his original band Creedence Clearwater Revival.



San Francisco's own "Southern" rockers, Creedence Clearwater Revival, scored a string of international hits during their brief existence, starting in 1967 and becoming classic rock staples despite performing only four years. So popular was CCR worldwide that by 1970 the group was consistently scoring hits on both the A and B sides of its singles, a feat previously accomplished only by Elvis Presley and the Beatles.



After the group split in October 16, 1972, Clifford teamed up with original CCR bass player Stu Cook and, both being the rhythm section of the Revival, went on to perform on and off on ex-CCR rhythm guitar Tom Fogerty's solo albums, who had quit CCR one year before it folded. Doug cowrote with Tom Fogerty the "Champagne Love" opening catchy tune for the latter's "Deal It Out" album.



After Creedence demise Clifford cut a solo album for Fantasy Records simply called "Doug 'Cosmo' Clifford". It is out of print at the moment of writing.



In 1974 Clifford produced for Doug Sahm the outstanding album "Groovers Paradise- Tex-Mex Trip" where he played the drums alongside Stu Cook's bass.



Clifford and Stu Cook joined the The Don Harrison Band-project playing drums and bass there in 1976. They released the album "The Don Harrison Band". This group received some coverage but it's momentum lasted only for follow-up album "Red Hot" and then it died.



Cosmo Clifford has had since a long standing collaboration with Doug Sahm. His last is on Sir Douglas Quintet's Day Dreaming at Midnight.



In 1995 Clifford and Stu Cook fronted Creedence Clearwater Revisited and began touring to date. After former original bandmate John Fogerty got in October 1996 an Injunction Order against them performing under that name pending final ruling on the trial scheduled for sometime in 1997, they were introduced as "Stu Cook and Doug Clifford Present The Music Of Creedence Clearwater Revival". Shortly thereafter they dropped it in favor of "Stu Cook and Doug Clifford present: Cosmo's Factory", Cosmo being of course the nickname of Doug Clifford as well as the title of Creedence Clearwater's fifth album.



Along with touring the world the band released a double live CD called "Recollection" in 1998.
