This piyyut, attributed to Menaḥem ben Aharon, is found in the Maḥzor Vitry, siman 465. It is a note-for-note structural parody of a beloved Pesaḥ maarava poem, Leil Shimurim. Israel Davidson, in his 1907 work “Parody in Jewish Literature,” writes, “The parodist apparently has no other aim than to dress a wine-song in the garb of a religious hymn. The burden of the song is that on Purim one must throw of all care and anxiety… But in order to make our happiness complete, we must remember the needy, and share our luxuries with those that are in want of them.”
