Collins, Miriam Makeba, Odetta, The Simon Sisters (Carly Simon), Buffy Sainte-Marie, Mary Travers, Joni Mitchell and Joan Baez. He represented Ireland's Clancy Brothers, Britain's Ewan MacColl, Donovan and Pentangle, and also had an eclectic international roster including Jacques Brel, Nana Mouskouri, Mercedes Sosa and Ravi Shankar. Leventhal produced concerts at venues such as Carnegie Hall for artists such as Pete Seeger, Johnny Cash, Bob Dylan, Neil Young, Phil Ochs, Arlo Guthrie, Peter Paul and Mary, Neil Diamond, Joan Baez, Joni Mitchell, Judy Collins, and many others. He had a knack for producing big shows that could focus the energy of an era. A birthday benefit concert for Martin Luther King Jr., at Carnegie Hall in January 1961, helped King appeal to the white general public. He produced fund raising tribute concerts for Phil Ochs, Paul Robeson, the Spanish civil war's Abraham Lincoln Brigade and, most memorably, for Woody Guthrie in March 1956 and then again, after Guthrie's death, in 1968 and 1970. After Guthrie's death in 1967, Leventhal virtually adopted Woody's son Arlo, who worked in his office before making his hit record Alice's Restaurant. He helped produce the film based on that song, and later co-produced the Oscar-winning Bound for Glory starring David Carradine as Woody Guthrie. Among his other films was the Pete Seeger documentary A Song and a Stone (1972), the Weavers documentary Wasn't that a Time! (1984) and the Emmy-winning We Shall Overcome (1988). Leventhal also produced theatre, starting with his fellow blacklister Will Geer performing Mark Twain's America off-Broadway in 1952. Harold Leventhal was also integrally involved in the theatrical and film careers of both Alan Arkin as well as Theodore Bikel. Reflecting his political and musical interests, he produced, among others, Joseph Heller's We Bombed in New Haven, Jules Epstein's But Seriously, Rabindranath Tagore's King of the Dark Chamber and Jules Feiffer's The White House Murder Case. Tribute In 2003, Leventhal received his own tribute concert at Carnegie Hall. A film of that show, Isn't this a Time, was released in 2004. Leventhal may have been defined best in the program notes for that concert, as embodying the definition of the Yiddish word, mensch, meaning "man" in the sense of "an upright, honorable, decent person, someone of noble character". American singer-songwriter, Guthrie Thomas, stated, "Harold Leventhal was an instrumental key in keeping the art of folk music alive in the eyes of many thousands
