Izlel ye Delyo Haydutin

"Izlel ye Delyo Haydutin" (Bulgarian: Излел е Дельо хайдутин, lit.'Delyo has become a hajduk') is a Bulgarian folk song from the central Rhodope Mountains about Delyo, a rebel leader who was active in the late seventeenth and early eighteenth centuries. The song is most famously sung by Valya Balkanska, a 1970 recording of which was included on the Golden Record carried on board the Voyager 1 and Voyager 2 probes.
