Creedence Clearwater Revival, commonly abbreviated as CCR or simply Creedence, was an American rock band formed in El Cerrito, California. The band consisted of lead vocalist, lead guitarist, and primary songwriter John Fogerty, his brother, rhythm guitarist Tom Fogerty, bassist Stu Cook, and drummer Doug Clifford. These members had played together since 1959, first as the Blue Velvets and later as the Golliwogs, before settling on Creedence Clearwater Revival in 1967. The band's most prolific and successful period between 1969 and 1971 produced fourteen consecutive Top 10 singles and five consecutive Top 10 albums in the United States – two of which, Green River (1969) and Cosmo's Factory (1970), reached number one. The band performed at the 1969 Woodstock festival in Upstate New York, and was the first major act signed to appear there.
