From the wiki: “‘Big Rock Candy Mountain’, first recorded by Harry McClintock in 1928, is a folk music song about a hobo’s idea of paradise – a place where ‘hens lay soft boiled eggs’ and there are ‘cigarette trees’. McClintock claimed to have written the song in 1895, based on tales from his youth hobo-ing through the United States, but some believe that at least aspects of the song have existed for far longer. McClintock was a member of the Industrial Workers of the World (I.W.W.), and the author of other labor songs as ‘Haywire Mac’, ‘Sam Bass’ and ‘Hallelujah Bum Again’. His original 1928 recording was used on the O Brother, Where Art Thou soundtrack (minus the plural form). The song achieved widespread popularity in 1949 when a sanitized version intended for children was recorded by Burl Ives. A version recorded in 1960 by Dorsey Burnette reached #102 on Billboard’s chart.
