Many thanks to SRAA contributor, Tom Gavaras, who shares the following recording and notes:

Notes: Studio recording of Polish Radio from 1977. The recording opens with the Polish Radio interval signal followed by a documentary called "In Defense of Peace." The program covers Poland during WWII including a few brief excerpts of Polish Radio and German radio, discussion on the start of the cold war, atomic weapons/arms race, Poland's pursuit of peace, etc. Music is interspersed through out the recording.
