Problem: Buffalo Springfield was a Canadian-American rock band active from 1966 to 1968 whose most prominent members were Stephen Stills, Neil Young, and Richie Furay. The band released three albums and several singles, including "For What It's Worth". The band combined elements of folk and country music with British invasion and psychedelic-rock influences, and, along with the Byrds, were part of the early development of folk-rock. With a name taken from a brand of steamroller, Buffalo Springfield formed in Los Angeles in 1966 with Stills (guitar, keyboards, vocals), Dewey Martin (drums, vocals), Bruce Palmer (electric bass), Furay (guitar, vocals), and Young (guitar, harmonica, piano, vocals).

Neil Young and Stephen Stills met in 1965, at the Fourth Dimension in Thunder Bay, Ontario. Young was there with the Squires, a Winnipeg group he had been leading since February 1963, and Stills was on tour with The Company, a spin-off from the Au Go Go Singers. When Stills' band broke up at the end of that tour, he moved to the West Coast, where he worked as a session musician and auditioned unsuccessfully for, among other bands, the Monkees. Told by record producer Barry Friedman there would be work available if he could assemble a band, Stills invited fellow Au Go Go Singers alumnus Richie Furay and former Squires bass player Ken Koblun to come join him in California. Both agreed, although Koblun chose to leave before very long and joined the group 3's a Crowd. In early 1966 in Toronto, Young met Bruce Palmer, a Canadian who was playing bass for a group called the Mynah Birds. In need of a lead guitarist, Palmer invited Young to join the group, and Young accepted. The Mynah Birds were set to record an album for Motown Records when their singer Ricky James Matthews--James Ambrose Johnson, Jr., later known as Rick James--was tracked down and arrested by the U.S. Navy for being AWOL. With their record deal canceled, Young and Palmer headed for Los Angeles, where they encountered Stills. Drummer Dewey Martin, who had played with garage rock group the Standells and country artists such as Patsy Cline and the Dillards, joined at the suggestion of the Byrds' manager, Jim Dickson. The group's name was taken from a brand of steamroller made by the Buffalo-Springfield Roller Company. The new group debuted on April 11, 1966, at The Troubadour in Hollywood. A few days later, they began a short tour of California as the opening act for the Dillards and the Byrds.

Problem: Abhay Charanaravinda Bhaktivedanta Swami Prabhupada (Abhoy Charonarobindo Bhoktibedanto Shwamy Probhupad; 1 September 1896 - 14 November 1977) was a Gaudiya Vaishnavism spiritual teacher (guru) and the founder preceptor (Acharya) of the International Society for Krishna Consciousness (ISKCON), commonly known as the "Hare Krishna Movement". Adherents of the ISKCON movement view Prabhupada as a divine avatar and messenger of Krishna. Born Abhay Charan De in Calcutta, he was educated at the Scottish Church College in Calcutta. Before adopting the life of a pious renunciant (vanaprastha) in 1950, he was married with children and owned a small pharmaceutical business.

In 1922, when he first met his spiritual master, Bhaktisiddhanta Sarasvati Thakura, he was requested to spread the message of Chaitanya Mahaprabhu in the English language. In 1933 he became a formally initiated disciple of Bhaktisiddhanta. In 1944, (from his front room at Sita Kanta Banerjee, Calcutta), he started the publication called Back to Godhead, for which he acted as writer, designer, publisher, editor, copy editor and distributor. He personally designed the logo, an effulgent figure of Chaitanya Mahaprabhu in the upper left corner, with the motto: "Godhead is Light, Nescience is darkness" greeting the readers. In his first magazine he wrote: Under the circumstances since 1936 up to now, I was simply speculating whether I shall venture this difficult task and that without any means and capacity; but as none have discouraged me, I have now taken courage to take up the work. In 1947, the Gaudiya Vaishnava Society recognised his scholarship with the title Bhaktivedanta, (bhakti-vedanta) meaning "one who has realised that devotional service to the Supreme Lord is the end of all knowledge" (with the words Bhakti, indicating devotion and Vedanta indicating conclusive knowledge). His later well known name, Prabhupada, is a Sanskrit title, literally meaning "he who has taken the shelter of the lotus feet of the Lord" where prabhu denotes "Lord", and pada means "taking shelter." Also, "at whose feet masters sit". This name was used as a respectful form of address by his disciples from late 1967 early 1968 onwards. Previous to this, as with his early disciples, followers used to call him "Swamiji". From 1950 onwards, he lived at the medieval Radha-Damodar mandir in the holy town of Vrindavan, where he began his commentary and translation work of the Sanskrit work Bhagavata Purana. Of all notable Vrindavana's temples, the Radha-Damodara mandir had at the time the largest collection of various copies of the original writings of the Six Gosvamis and their followers - more than two thousand separate manuscripts, many of them three hundred, some even four hundred years old. His guru, Bhaktisiddhanta Sarasvati Thakura, had always encouraged him to print books, and beholding his spiritual master, Abhay felt the words deeply enter his own life - "If you ever get money, print books." referring to the need of literary presentation of the Vaishnava culture.
