IIRC,Zaentz sued Fogerty for supposedly plagiarizing himself The Old Man Down The Road, from Run Through The Jungle) as Fantasy held the publishing on the old CCR songs Fogerty wrote. Fogerty successfully defended himself in court, playing music live in the courtroom and giving lessons on what constituted a musician's style, which would cross over individual compositions. Fogerty countersued for damages, and won - that case went to the supreme court. I still listen to CCR sometimes, but generally the longer deep cuts rather than the hits. His later albums were good, but his era had passed.
