Frankfurt, 1937: The world premiere of Carl Orff’s scenic cantata "Carmina Burana". This oratorio is based on a manuscript of poems from 11th – 13th century (Mostly in Medieval Latin), full of the impressions of the ephemeral life that must be therefore compensated by love, joy and lust, and the pleasures of drinking and gambling. Powerful Orff's choir music I see personally as a predecessor to the rock musical "Hair", from 1967 (Lyrics by James Rado and Gerome Ragni and music by Galt MacDermot). Milos Forman's film adaptation of musical "Hair" from 1979 is for me full of the atmosphere of "Carmina Burana" (The long-haired hippies with marijuana instead of Burana's vagabonds drinking vine). The final scenes of the film when George (Treat Williams) is marching, instead of Claude, with hundreds of soldiers into the darkness of the huge airplane to Vietnam, with the song "Let the Sunshine In", is a Forman's miraculous way to tell us a modern, sad story of the Wheel of Fortuna from "Carmina Burana".
