Did you know ? (38)
According To the Mishna Verurah (295 sk3) This coming Motzei Shabbos we do say Vihi Noam. Erev Pesach is considered only a minor Yom Tov, not enough to refrain from saying Vihi Noam.
The Sheilos Yavetz (19) holds we do not say Vehi Noiam when Erev Pesach falls out on a Friday (since there is an Issur Melacha on E. Pesach)
