His raw, soulful voice and intense physical performance - complete with his signature wild, jerking dance movements - turned the Beatles' friendly tune into a gospel-tinged anthem of brotherhood.

At dawn on Monday morning, after most of the crowd had departed, Jimi Hendrix delivered what would become the festival's most iconic moment - his explosive interpretation of "The Star-Spangled Banner." The performance, to a weary crowd of 30,000 remaining attendees, captured both the beauty and chaos of the era through his masterful distortion and effects.

Crosby, Stills & Nash (with Neil Young) took the stage for one of their earliest live performances. Despite their nerves, "Suite: Judy Blue Eyes" floated across the farm, their pristine harmonies a testament to their musical chemistry even in those early days.

A relatively unknown Santana electrified the crowd with "Soul Sacrifice." The combination of Carlos Santana's blistering guitar work and Michael Shrieve's thunderous drum solo - performed when he was just 20 years old - launched the band into stardom.

Joan Baez, six months pregnant and without her imprisoned husband David Harris, delivered a moving performance of "I Shall Be Released" in the rain during the early hours. Her crystal-clear voice and unwavering commitment to social justice embodied the festival's spirit of peace and protest.

Jefferson Airplane's Grace Slick led the crowd through a powerful "Volunteers" as the sun rose on Sunday morning, the song's revolutionary spirit capturing the political energy of the era.

The Band brought their rootsy Americana to the festival with "The Weight," offering a moment of storytelling amid the psychedelic chaos.

Janis Joplin's raw, emotional delivery of "Work Me, Lord" showcased her incredible vocal power and deep connection to the blues.

Richie Havens opened the festival after being helicoptered in when other acts were stuck in traffic. When he ran out of songs during his extended set, he improvised "Freedom" on the spot - creating one of the festival's most memorable moments through pure necessity.

The weekend also saw The Who playing through dawn, their performance of "Tommy" punctuated by Abbie Hoffman's infamous stage invasion and Pete Townshend's equally infamous response.

Sly & the Family Stone delivered an electrifying late-night set that had the muddy crowd dancing to "I Want to Take You Higher," while Country Joe McDonald led hundreds of thousands in the "Fish Cheer" before launching into "I-Feel-Like-I'm-Fixin'-to-Die Rag."
