The following version of the very popular Shalom Aleichem which is part of the Sabbath evening liturgy is sung to a Spanish-Moroccan tune. Spanish Jews settled in North Africa in the aftermath of the Expulsion in 1492. Culturally, they formed a unique subset of North African Jewry even while their scholars dominated Jewish jurisprudence.
Many of the great rabbis that discussed Conversos and Crypto-Jews settled in North Africa. This includes Rabbi Isaac Bar Sheshet Perfet as well as various rabbis of the Duran clan.
