Thanks to Andy McCord for pointing to this group interview of Faiz from 1974 on Youtube. As he puts it: The interviews get more into Faiz's literary views, influences and practices than do the print interviews I'm aware of and may be of great interest to the Faiz admirers on this list. He coins a term for his practice: "political lyricism, if you want to call it that."
The interview is uploaded by radiopakistanonline and, as per mentioned details, was recorded as part of the programme Fun aur Funkar on October 5, 1974. The interviewers are Sufi Ghulam Mustafa Tabassum, Hameed Akhtar, Qayyum Nazar, Sajjad Baqar Rizvi, Anees Nagi, Intizar Hussain, Aijaz Hussain Batalvi, Munnu Bhai
