This is part of the documentary "I Athina ti nihta" ("Athens by night"), filmed in 1962. Grigoris Bithikotsis sings "i Margarita, i Margaro", and Giota Lydia sings "Stin Kokkinia". In the second song you can easily recognize a part of famous "Zorba". Theodorakis had also used it in a Greek movie of 1961 ("Sinikia to oniro"), before "Zorba" (1964).
