I will say this. I would be disappointed in any Yeshivah that did not have some sort of Divrei Hesped for R’ Ovadia or R’ Elyashiv. Any Yeshivah, no matter how big or small.
HaLeivi: Maybe a moment of silence wouldn’t have been so inappropriate. There is a T’shuvah in the Yaskil Avdi that brings Mekoros that a moment of silence is a legitimate Jewish way to commemorate something. I know R’ Ovadia quoted this T’shuvah, but I don’t remember if he was pro or con.
