here's what it says about the program:

"It was the year the Vietnam war came home, when the peaceful ideals of the '60s gave way to horror. Anti-war activists protesting the invasion of Cambodia found themselves being gunned down for their beliefs. CSNY memorialized the Kent State tragedy in the song "Ohio." 1970 was also the year that generational icons Jimi Hendrix and Janis Joplin fell victim to their excesses, and the Beatles collapsed under the weight of their enormous popularity. In California, good vibrations soured when failed rock musician Charles Manson struck back against an industry which didn't understand his "genius"; the mayhem he orchestrated became forever linked to the Beatles song "Helter Skelter." The counterculture found itself guilty by association, and "save the world" turned into "save yourself." Introspective singer/songwriters like James Taylor and Joni Mitchell replaced revolutionary rockers; Simon & Garfunkel's "Bridge Over Troubled Water," certainly a cry of help, was the song of 1970. BTM looks back at this pivotal year with archival footage, journalistic commentary, and interviews with Paul McCartney, David Crosby, Judy Collins, former Sen. Tom Hayden, and many others."
