“Country” Joe McDonald, a hippie rock star of the 1960s whose “I-Feel-Like-I’m-Fixin’-To-Die Rag” was a four-lettered rebuke to the Vietnam War that became an anthem for protesters and a highlight of the Woodstock music festival, died Sunday at 84. His death from complications of Parkinson’s disease was reported by his wife of 43 years, Kathy McDonald. The performer was a longtime presence in the Bay Area music scene, where peers included the Grateful Dead, the Jefferson Airplane and his onetime girlfriend, Janis Joplin. He wrote or co-wrote hundreds of songs, from psychedelic jams to soul-influenced rockers, and released dozens of albums.
