Dixie Yid has done the almost impossible (again). He posted the official write-up of Rav Weinberger’s Shabbos HaGadol drasha, here. Seems the drasha was on Shabbos this year. In the past it has been Motzei Shabbos and the mp3 has been available the next day.
While I have yet to read it (it’s printed and sitting in my car), I know that Dixie Yid takes great care in writing up the Torah of his Rebbe. I know that this must have taken a huge chunk of time and you have to go to Dixie Yid’s blog and check it out.
