Yarrow co-wrote (with Leonard Lipton) one of the group's greatest hits, "Puff, the Magic Dragon".

The word "hippie" came from "hipster" and was initially used to describe beatniks who had moved into New York City's Greenwich Village and San Francisco's Haight-Ashbury district. The term "hippie" was first popularized in San Francisco by Herb Caen, who was a journalist for the "San Francisco Chronicle". - The Byrds were an American rock band, formed in Los Angeles, California in 1964. The band underwent multiple lineup changes throughout its existence, with frontman Roger McGuinn (known as Jim McGuinn until mid-1967) remaining the sole consistent member, until the group disbanded in 1973. Although they only managed to attain the huge commercial success of contemporaries like the Beatles, the Beach Boys, and the Rolling Stones for a short period in late 1965, the Byrds are today considered by critics to be one of the most influential bands of the 1960s. Initially, they pioneered the musical genre of folk rock, melding the influence of the Beatles and other British Invasion bands with contemporary and traditional folk music. As the 1960s progressed, the band was also influential in originating psychedelic rock, raga rock, and country rock. - Haight-Ashbury is a district of San Francisco, California, named for the intersection of Haight and Ashbury streets.

It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam.
