Here is an audio recording of the lecture delivered Thursday night last week by R. Yehiel Goldhaber at the home of Dr. Shlomo Sprecher. Unfortunately, the recording is not complete, and the last 10-15 minutes of the lecture are missing. Since no other recording was posted online, I'm posting this incomplete recording. If the complete recording will be uploaded, I will update this post to include a link to the entire lecture. Feel free to download and share. The lecture was advertised in advanced on the Seforim Blog, and according to what it says there, it was dedicated to the memory of R. Y. Szlafrok, z"l whose 25th Yahrzeit was this past Shabbos, 10 Iyaar. יהא זכרו ברוך.
