Answer by taking a quote from the following article:

Fogerty was born in Berkeley, California, and grew up in El Cerrito, California, one of five sons born to Galen Robert and Edith Lucile Fogerty. His father, Galen Fogerty, was a native of South Dakota and worked as a Linotype operator for the Berkeley Gazette. Lucile Fogerty was from Great Falls, Montana. When John was two years old his parents both converted to Catholicism.

Fogerty was discharged from the Army in July 1967. In the same year, the band changed its name to Creedence Clearwater Revival. At this time, he took his brother's place as lead singer for the band. By 1968, things started to pick up for the band. The band released their eponymous debut album and also had their first hit single, "Susie Q". Many other hit singles and albums followed, beginning with "Proud Mary" and the album Bayou Country. Fogerty, as writer of the songs for the band (as well as lead singer and lead guitarist), felt that his musical opinions should count for more than those of the others, leading to resentments within the band. These internal rifts, and Tom's feeling that he was being taken for granted, caused Tom to leave the group in January 1971. The two other group members, bassist Stu Cook and drummer Doug Clifford, wanted a greater role in the band's future. Fogerty, in an attempt to keep things together, insisted Cook and Clifford share equal songwriting and vocal time on what became the band's final album, Mardi Gras, released in April 1972, which included the band's last two singles, the 1971 hit "Sweet Hitch-Hiker", and "Someday Never Comes", which barely made it into the Billboard Top 20. Cook and Clifford told Fogerty that the fans would not accept "Mardi Gras" as a CCR LP, but he said, "My voice is a unique instrument, and I will not lend it to your songs." He gave them an ultimatum: either they would do it or he would quit immediately. They accepted his ultimatum, but the album received poor reviews. It was a commercial success, however, peaking at #12 and achieving gold record status. It generated weaker sales than their previous albums. The group disbanded shortly afterwards. The only reunion of all four original members was at Tom Fogerty's wedding in 1980. Fogerty, Doug and Stu played a 45-minute set at their 20th class reunion in 1983, and Fogerty and Doug were reunited again for a brief set at their 25th class reunion.

Did the band break up?
The group disbanded shortly afterwards.
