Mi She'asa Nissim

They say that one Shabbos, Reb Sholom Halevi Brochshtat, had some L'chaim in shul and fell asleep. By the time he woke up, everyone left and locked the doors. What do you do when you are all alone in a shul? Compose a niggun! So he composed a niggun with the words that we say on Shabbos Mivorchim:

מִי שֶׁעָשָֹה נִסִּים לַאֲבותֵינוּ, וְגָאַל אוׂתָם מֵעַבְדוּת לְחֵרוּת, הוּא יִגְאַל אוׂתָנוּ בְּקָרוׂב, וִיקַבֵּץ נִדָּחֵינוּ מֵאַרְבַּע כַּנְפוׂת הָאָרֶץ, חֲבֵרִים כָּל יִשרָאֵל, וְנׂאמַר אָמֵן.

May He who performed miracles for our fathers, and redeemed them from slavery to freedom, speedily redeem us and assemble our dispersed people from the four corners of the earth, all of Israel should be united; and let us say Amen.
