What are some lost pieces of Punjabi media?

What media pieces of Punjabi media are out there lost in the time, which you wish could be found again and brought back? A few examples that come to my mind are - Shiv Kumar Batalvi's recordings, Amitabh Bachhan's Doordarshan speech during 1984's Sikh genocide. Suggest and bring up more of lost Punjabi media that we might be unaware of.
